The GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated is an issue that affects FileZilla users who are trying to download files from servers using explicit TLS. This error occurs when the server fails to properly terminate the TLS connection, causing the client (FileZilla) to assume the connection was closed prematurely.

This error can be frustrating for users as it prevents them from successfully downloading certain files. However, by following the steps outlined in this guide, you should be able to resolve the issue and download all files without any problems.

💡 Why You Are Getting This Error

  • The primary reason for this error is that the server's implementation of TLS may not be properly configured or may have a bug that causes it to fail. This can happen even if the server appears to be functioning correctly, making it difficult to diagnose and resolve the issue.
  • Another possible cause could be issues with the client-side configuration or settings in FileZilla. However, since you mentioned that many files download just fine, this is less likely to be the case.

🛠️ Step-by-Step Verified Fixes

Editing file contents to remove hard tabs

  1. Step 1: Open the problematic files on the server and replace all hard tabs (character 9) with 4 spaces. This should resolve the issue.
  2. Step 2: Save the changes to the files and then try downloading them again using FileZilla. If the problem persists, repeat the process for each file that has had issues.
  3. Step 3: After making these changes, you may need to reconfigure your server or adjust other settings to ensure that it is properly handling TLS connections. However, this step should help resolve the issue with files containing hard tabs.

Checking server logs and configuration

  1. Step 1: Check the server's error logs to see if there are any other errors or warnings that could be related to the TLS connection. This may provide additional clues about what is causing the issue.
  2. Step 2: Verify that the server's TLS configuration is properly set up and configured. Make sure that the server is using a valid certificate and that the TLS version being used is compatible with FileZilla.

💡 Conclusion

By following these steps, you should be able to resolve the GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated issue and download all files without any problems. Remember to regularly check your server's logs and configuration to ensure that it is properly handling TLS connections.
