How to Fix: How can I fix the "remote proxy closed the connection" error in X2Go?
Troubleshooting X2Go connection issues with authentication credentials and session logs.
📋 Table of Contents
The 'remote proxy closed the connection' error in X2Go occurs when the remote proxy server closes the connection while negotiating the session, often due to incorrect authentication credentials or issues with the session files. This error affects users who are trying to access remote desktops using X2Go and can be frustrating as it prevents them from accessing their remote sessions.
Understanding the logs and error messages is crucial in resolving this issue. The error message indicates that there was a wrong version or invalid session authentication cookie, which suggests that the problem may lie with the authentication keys or the session files.
⚠️ Common Causes
- One of the primary reasons for this error is incorrect authentication credentials. If the username, password, or private key used to connect to the server are incorrect, the remote proxy server will close the connection. This can happen due to typos, forgotten passwords, or changes in the authentication settings.
- Another possible reason for this error is issues with the session files. Corrupted or outdated session files can cause problems when trying to access a remote desktop using X2Go. In such cases, deleting the session files and reconfiguring the connection may resolve the issue.
🔧 Proven Troubleshooting Steps
Verify and update authentication credentials
- Step 1: Check the username and password used to connect to the server to ensure they are correct. If using a private key, verify that it is in the correct format and has not been corrupted.
- Step 2: Compare the X2Go settings with the NxMachine settings to ensure consistency between the two. Make sure the authentication method (password or private key) matches the one used by NxMachine.
- Step 3: If using a password, try resetting the password for the server user account and then reconnecting to the server using X2Go.
Delete corrupted session files
- Step 1: Locate the .x2go folder on your Windows laptop (usually C:/Users/MyUserName/.x2go/) and delete any existing session files. This may help resolve issues with corrupted or outdated session files.
- Step 2: Check for any old or deleted session files in the NxMachine connection directory (~/.x2go/). If found, delete them to ensure consistency between X2Go and NxMachine settings.
🎯 Final Words
To fix the 'remote proxy closed the connection' error in X2Go, verify and update authentication credentials, and consider deleting corrupted session files. By following these steps, you should be able to resolve the issue and regain access to your remote desktop sessions.
