Are you tired of waiting for your files to upload to BackBlaze B2 Cloud Storage, only to be left staring at a spinning wheel of doom? You’re not alone! In this article, we’ll dive into the common issues that cause the b2_upload_file endpoint to hang endlessly and provide you with actionable steps to troubleshoot and resolve the problem.
What is the b2_upload_file Endpoint?
The b2_upload_file endpoint is a crucial part of the BackBlaze B2 API, allowing developers to upload files to their cloud storage buckets. It’s a simple, yet powerful endpoint that enables seamless file transfers to the cloud. However, when it hangs, it can bring your entire application to a grinding halt.
Common Causes of the b2_upload_file Endpoint Hang
Before we dive into the troubleshooting steps, let’s take a look at some common causes of the b2_upload_file endpoint hang:
- Network Connectivity Issues: Slow or unstable internet connections can cause the endpoint to hang indefinitely.
- File Size and Type: Uploading large files or files with unsupported formats can lead to hangs.
- : Invalid or expired API keys, incorrect bucket names, or missing permissions can cause the endpoint to hang.
- : BackBlaze B2 server maintenance, outages, or high traffic can cause the endpoint to hang.
Troubleshooting Steps
Now that we’ve covered the common causes, let’s walk through a step-by-step troubleshooting process to resolve the b2_upload_file endpoint hang:
Step 1: Check Network Connectivity
Verify your internet connection speed and stability using a tool like speedtest.net. Ensure your network meets the minimum requirements for uploading files to BackBlaze B2.
// Sample code to check network speed in Python
import speedtest
servers = []
s = speedtest.Speedtest()
s.get_servers(servers)
s.get_best_server()
s.download()
s.upload()
s.results.share()
Step 2: Verify File Size and Type
Check the file size and type you’re attempting to upload. Ensure the file is within the supported size limits (5TB for BackBlaze B2) and in a supported format.
| File Type | Supported |
|---|---|
| Images (JPG, PNG, GIF) | |
| Videos (MP4, AVI, MOV) | |
| Documents (PDF, DOCX, XLSX) | |
| Archive Files (ZIP, RAR, TAR) |
Step 3: Verify Authentication and Authorization
Double-check your API key, bucket name, and account ID. Ensure you have the correct permissions to upload files to your BackBlaze B2 bucket.
// Sample code to authenticate with BackBlaze B2 in Python
import b2
b2_api = b2.B2Api(account_id='your_account_id', application_key='your_application_key')
bucket_name = 'your_bucket_name'
bucket = b2_api.get_bucket_by_name(bucket_name)
Step 4: Check BackBlaze B2 Server Status
Visit the BackBlaze B2 Status Page to check for any ongoing maintenance or outages.
Step 5: Enable Debug Logging
Enable debug logging to capture detailed information about the upload process. This will help you identify any errors or issues occurring during the upload.
// Sample code to enable debug logging in Python
import logging
logging.basicConfig(level=logging.DEBUG)
Step 6: Test the b2_upload_file Endpoint
Use a tool like curl or a Python script to test the b2_upload_file endpoint. This will help you isolate the issue and identify any errors.
// Sample code to test the b2_upload_file endpoint using curl
curl -X POST \
https://api.backblaze.com/b2api/v2/b2_upload_file \
-H 'Authorization: YOUR_AUTHORIZATION_TOKEN' \
-H 'Content-Type: application/json' \
-d '{"bucketId": "YOUR_BUCKET_ID", "fileName": "example.txt", "contentType": "text/plain", "file": "YOUR_FILE_CONTENTS"}'
Conclusion
In conclusion, the b2_upload_file endpoint hang can be frustrating, but by following these troubleshooting steps, you should be able to identify and resolve the issue. Remember to check your network connectivity, file size and type, authentication and authorization, BackBlaze B2 server status, and enable debug logging to capture detailed information about the upload process.
By following these steps, you’ll be able to successfully upload files to your BackBlaze B2 bucket and ensure your application runs smoothly. Happy coding!

Frequently Asked Question
Having trouble with the b2_upload_file endpoint hanging endlessly? You’re not alone! Here are some frequently asked questions to help you troubleshoot the issue:
Why does the b2_upload_file endpoint hang indefinitely?
This can happen when the upload connection is lost or interrupted, causing the endpoint to wait for the remaining data to be sent. Check your internet connection, and try re-uploading the file after resolving any connectivity issues.
Is there a file size limit that could cause the endpoint to hang?
Yes, BackBlaze B2 has a maximum file size limit of 5TB. If you’re uploading a file larger than this, the endpoint may hang. Try breaking down large files into smaller chunks or use the BackBlaze B2 Large File Upload API.
Can network congestion or high latency cause the b2_upload_file endpoint to hang?
Absolutely! Network congestion, high latency, or packet loss can all contribute to the endpoint hanging. Try uploading during off-peak hours or optimizing your network configuration to improve performance.
Are there any specific error messages that can indicate why the b2_upload_file endpoint is hanging?
Yes, look out for error messages like “connection reset by peer” or “connection timed out”. These can indicate issues with the connection or upload process. Check the BackBlaze B2 API documentation for more information on error codes and troubleshooting.
Is there a timeout value I can set to prevent the b2_upload_file endpoint from hanging indefinitely?
Yes, you can set a timeout value when uploading files to BackBlaze B2. This will allow you to cancel the upload if it takes too long. Check the BackBlaze B2 API documentation for more information on setting timeouts.
