This page describes troubleshooting methods for common errors yous may encounter while using Cloud Storage.

Run into the Google Deject Status Dashboard for information virtually regional or global incidents affecting Google Deject services such as Cloud Storage.

Logging raw requests

When using tools such every bit gsutil or the Cloud Storage client libraries, much of the request and response information is handled by the tool. However, it is sometimes useful to see details to aid in troubleshooting. Use the following instructions to return asking and response headers for your tool:

Console

Viewing request and response information depends on the browser you're using to access the Google Cloud Console. For the Google Chrome browser:

1. Click Chrome's main menu push button ().

2. Select More than Tools.

3. Click Programmer Tools.

4. In the pane that appears, click the Network tab.

gsutil

Apply the global -D flag in your request. For instance:

gsutil -D ls gs://my-bucket/my-object

Client libraries

C++

• Set the environment variable CLOUD_STORAGE_ENABLE_TRACING=http to get the full HTTP traffic.

• Set the surround variable CLOUD_STORAGE_ENABLE_CLOG=yes to get logging of each RPC.

C#

Add a logger via ApplicationContext.RegisterLogger, and fix logging options on the HttpClient bulletin handler. For more than information, encounter the FAQ entry.

Go

Set the surroundings variable GODEBUG=http2debug=1. For more information, see the Go packet net/http.

If you want to log the request body also, use a custom HTTP client.

Java

1. Create a file named "logging.properties" with the post-obit contents:

   # Properties file which configures the operation of the JDK logging facility. # The system volition look for this config file to be specified as a arrangement property: # -Djava.util.logging.config.file=${project_loc:googleplus-simple-cmdline-sample}/logging.properties  # Set up the console handler (uncomment "level" to show more than fine-grained messages) handlers = coffee.util.logging.ConsoleHandler java.util.logging.ConsoleHandler.level = CONFIG  # Set up logging of HTTP requests and responses (uncomment "level" to prove) com.google.api.client.http.level = CONFIG

2. Use logging.backdrop with Maven

   mvn -Djava.util.logging.config.file=path/to/logging.properties                      insert_command                    

For more information, see Pluggable HTTP Transport.

Node.js

Set the environment variable NODE_DEBUG=https before calling the Node script.

PHP

Provide your own HTTP handler to the client using httpHandler and fix middleware to log the request and response.

Python

Use the logging module. For instance:

import logging import http.client  logging.basicConfig(level=logging.DEBUG) http.customer.HTTPConnection.debuglevel=5

Ruby

At the height of your .rb file after require "google/cloud/storage", add together the following:

scarlet Google::Apis.logger.level = Logger::DEBUG

Fault codes

The post-obit are common HTTP status codes you may encounter.

301: Moved Permanently

Outcome: I'm setting up a static website, and accessing a directory path returns an empty object and a 301 HTTP response code.

Solution: If your browser downloads a zero byte object and yous go a 301 HTTP response lawmaking when accessing a directory, such as http://world wide web.instance.com/dir/, your saucepan most probable contains an empty object of that name. To bank check that this is the case and fix the issue:

1. In the Google Deject Panel, go to the Cloud Storage Browser page.

   Go to Browser

2. Click the Activate Deject Trounce button at the top of the Google Cloud Console.
3. Run gsutil ls -R gs://world wide web.case.com/dir/. If the output includes http://world wide web.case.com/dir/, you have an empty object at that location.
4. Remove the empty object with the command: gsutil rm gs://world wide web.example.com/dir/

You can now admission http://www.example.com/dir/ and have it return that directory's alphabetize.html file instead of the empty object.

400: Bad Asking

Upshot: While performing a resumable upload, I received this error and the message Failed to parse Content-Range header.

Solution: The value yous used in your Content-Range header is invalid. For case, Content-Range: */* is invalid and instead should be specified every bit Content-Range: bytes */*. If you receive this error, your current resumable upload is no longer active, and you must start a new resumable upload.

Upshot: Requests to a public bucket directly, or via Cloud CDN, are failing with a HTTP 401: Unauthorized and an Hallmark Required response.

Solution: Check that your client, or any intermediate proxy, is not adding an Say-so header to requests to Cloud Storage. Whatever request with an Authorization header, even if empty, is validated as if it were an authentication endeavor.

403: Account Disabled

Issue: I tried to create a bucket but got a 403 Account Disabled fault.

Solution: This mistake indicates that you have not yet turned on billing for the associated projection. For steps for enabling billing, come across Enable billing for a project.

If billing is turned on and you continue to receive this error bulletin, you can reach out to back up with your projection ID and a clarification of your problem.

403: Access Denied

Issue: I tried to list the objects in my bucket simply got a 403 Access Denied error and/or a message like to Anonymous caller does non have storage.objects.listing admission.

Solution: Cheque that your credentials are right. For instance, if y'all are using gsutil, check that the credentials stored in your .boto file are authentic. As well, ostend that gsutil is using the .boto file you lot expect by using the control gsutil version -l and checking the config path(s) entry.

Assuming you are using the correct credentials, are your requests existence routed through a proxy, using HTTP (instead of HTTPS)? If so, check whether your proxy is configured to remove the Authorization header from such requests. If and then, make sure you are using HTTPS instead of HTTP for your requests.

403: Forbidden

Issue: I am downloading my public content from storage.cloud.google.com, and I receive a 403: Forbidden mistake when I use the browser to navigate to the public object:

https://storage.cloud.google.com/BUCKET_NAME/OBJECT_NAME        

Solution: Using storage.cloud.google.com to download objects is known as authenticated browser downloads; it ever uses cookie-based authentication, even when objects are made publicly accessible to allUsers. If y'all have configured Data Access logs in Deject Audit Logs to track admission to objects, one of the restrictions of that characteristic is that authenticated browser downloads cannot exist used to admission the affected objects; attempting to practise so results in a 403 response.

To avert this issue, exercise one of the following:

• Utilise direct API calls, which support unauthenticated downloads, instead of using authenticated browser downloads.
• Disable the Deject Storage Data Access logs that are tracking admission to the affected objects. Exist enlightened that Data Admission logs are set at or in a higher place the project level and tin be enabled simultaneously at multiple levels.
• Gear up Information Access log exemptions to exclude specific users from Information Access log tracking, which allows those users to perform authenticated browser downloads.

409: Conflict

Event: I tried to create a bucket only received the following error:

409 Disharmonize. Sorry, that name is non available. Please attempt a different one.

Solution: The bucket name you tried to use (e.chiliad. gs://cats or gs://dogs) is already taken. Cloud Storage has a global namespace so yous may non name a bucket with the same name as an existing saucepan. Choose a name that is non being used.

429: Besides Many Requests

Issue: My requests are existence rejected with a 429 Too Many Requests error.

Solution: You are hitting a limit to the number of requests Deject Storage allows for a given resources. Run into the Cloud Storage quotas for a discussion of limits in Cloud Storage. If your workload consists of 1000's of requests per second to a bucket, see Request rate and access distribution guidelines for a word of best practices, including ramping upwardly your workload gradually and avoiding sequential filenames.

Diagnosing Google Cloud Panel errors

Issue: When using the Google Cloud Console to perform an operation, I get a generic error message. For example, I run into an mistake message when trying to delete a saucepan, merely I don't see details for why the operation failed.

Solution: Utilise the Google Cloud Console's notifications to see detailed data about the failed performance:

1. Click the Notifications push in the Google Deject Panel header.

   

   A dropdown displays the most recent operations performed by the Google Cloud Console.

2. Click the particular yous want to find out more about.

   A page opens upward and displays detailed information about the operation.

3. Click on each row to expand the detailed error information.

   Below is an case of mistake information for a failed bucket deletion operation, which explains that a bucket retention policy prevented the deletion of the saucepan.

   

gsutil errors

The following are mutual gsutil errors you may encounter.

gsutil stat

Upshot: I tried to use the gsutil stat command to brandish object status for a subdirectory and got an error.

Solution: Deject Storage uses a flat namespace to store objects in buckets. While you can use slashes ("/") in object names to brand it announced as if objects are in a hierarchical structure, the gsutil stat command treats a trailing slash as part of the object name.

For example, if y'all run the command gsutil -q stat gs://my-bucket/my-object/, gsutil looks up information about the object my-object/ (with a trailing slash), equally opposed to operating on objects nested nether my-bucket/my-object/. Unless you actually have an object with that proper noun, the functioning fails.

For subdirectory listing, apply the gsutil ls instead.

gcloud auth

Issue: I tried to authenticate gsutil using the gcloud auth command, but I even so cannot access my buckets or objects.

Solution: Your system may accept both the stand up-alone and Google Cloud CLI versions of gsutil installed on it. Run the command gsutil version -l and check the value for using cloud sdk. If False, your system is using the stand-alone version of gsutil when you run commands. Y'all can either remove this version of gsutil from your system, or yous can authenticate using the gsutil config control.

Static website errors

The following are mutual bug that you may encounter when setting upwardly a bucket to host a static website.

HTTPS serving

Issue: I want to serve my content over HTTPS without using a load balancer.

Solution: You lot can serve static content through HTTPS using direct URIs such as https://storage.googleapis.com/my-bucket/my-object. For other options to serve your content through a custom domain over SSL, you can:

• Use a third-party Content Commitment Network with Cloud Storage.
• Serve your static website content from Firebase Hosting instead of Deject Storage.

Domain verification

Issue: I tin can't verify my domain.

Solution: Usually, the verification process in Search Console directs y'all to upload a file to your domain, but y'all may not take a mode to do this without offset having an associated bucket, which you tin can merely create afterward you accept performed domain verification.

In this instance, verify buying using the Domain name provider verification method. Meet Ownership verification for steps to reach this. This verification can be done before the bucket is created.

Inaccessible folio

Issue: I become an Access denied error bulletin for a web page served by my website.

Solution: Check that the object is shared publicly. If it is not, meet Making Data Public for instructions on how to do this.

If you previously uploaded and shared an object, just and so upload a new version of it, then you must reshare the object publicly. This is because the public permission is replaced with the new upload.

Permission update failed

Issue: I get an mistake when I attempt to make my data public.

Solution: Make sure that you lot have the setIamPolicy permission for your object or saucepan. This permission is granted, for example, in the Storage Admin role. If you have the setIamPolicy permission and y'all yet get an error, your saucepan might exist discipline to public admission prevention, which does not allow access to allUsers or allAuthenticatedUsers. Public admission prevention might be set on the bucket directly, or it might be enforced through an organization policy that is set at a college level.

Content download

Issue: I am prompted to download my page'south content, instead of being able to view it in my browser.

Solution: If you specify a MainPageSuffix as an object that does not take a web content type, and then instead of serving the page, site visitors are prompted to download the content. To resolve this issue, update the content-blazon metadata entry to a suitable value, such as text/html. See Editing object metadata for instructions on how to practise this.

Latency

The following are mutual latency bug y'all might encounter. In addition, the Google Cloud Status Dashboard provides data about regional or global incidents affecting Google Deject services such as Cloud Storage.

Upload or download latency

Outcome: I'g seeing increased latency when uploading or downloading.

Solution: Apply the gsutil perfdiag command to run performance diagnostics from the afflicted environment. Consider the following mutual causes of upload and download latency:

• CPU or memory constraints: The affected environment'southward operating system should take tooling to measure local resource consumption such equally CPU usage and memory usage.

• Disk IO constraints: As part of the gsutil perfdiag command, utilize the rthru_file and wthru_file tests to gauge the functioning affect acquired by local disk IO.

• Geographical altitude: Performance can be impacted by the physical separation of your Cloud Storage bucket and afflicted surround, particularly in cross-continental cases. Testing with a bucket located in the aforementioned region equally your afflicted environment tin can identify the extent to which geographic separation is contributing to your latency.

  • If applicative, the affected surround's DNS resolver should use the EDNS(0) protocol then that requests from the environment are routed through an appropriate Google Front end Terminate.

gsutil or client library latency

Event: I'thou seeing increased latency when accessing Cloud Storage with gsutil or one of the customer libraries.

Solution: Both gsutil and customer libraries automatically retry requests when it's useful to do and so, and this beliefs tin finer increase latency equally seen from the end user. Use the Cloud Monitoring metric storage.googleapis.com/api/request_count to see if Cloud Storage is consistenty serving a retryable response code, such as 429 or 5xx.

Proxy servers

Issue: I'm connecting through a proxy server. What exercise I need to do?

Solution: To access Cloud Storage through a proxy server, you must permit access to these domains:

• accounts.google.com for creating OAuth2 authentication tokens via gsutil config
• oauth2.googleapis.com for performing OAuth2 token exchanges
• *.googleapis.com for storage requests

If your proxy server or security policy doesn't support whitelisting by domain and instead requires whitelisting by IP network block, we strongly recommend that you configure your proxy server for all Google IP address ranges. You can find the address ranges past querying WHOIS data at ARIN. As a best practice, you lot should periodically review your proxy settings to ensure they friction match Google'due south IP addresses.

We practice not recommend configuring your proxy with private IP addresses you obtain from 1-fourth dimension lookups of oauth2.googleapis.com and storage.googleapis.com. Because Google services are exposed via DNS names that map to a large number of IP addresses that can change over fourth dimension, configuring your proxy based on a erstwhile lookup may lead to failures to connect to Deject Storage.

If your requests are being routed through a proxy server, y'all may need to check with your network administrator to ensure that the Authorization header containing your credentials is not stripped out by the proxy. Without the Authority header, your requests are rejected and you lot receive a MissingSecurityHeader mistake.
