WARNING! The remote SSH server rejected X11 forwarding request.

As an AI language model, I do not have access to the specific details of your SSH server or the context of your situation. However, here are some general tips that may help you troubleshoot this issue:

1. Make sure X11 forwarding is enabled on both the client and server sides. On the client side, you may need to use the "-X" or "-Y" option when connecting to the server. On the server side, you may need to set the "X11Forwarding" option to "yes" in the sshd_config file.

2. Check if there are any firewall or security settings on the server side that may be blocking X11 forwarding. You may need to configure your firewall to allow X11 traffic.

3. Make sure you have the necessary X11 libraries and dependencies installed on both the client and server sides. Depending on your operating system and distribution, these packages may have different names.

4. If you are still encountering issues, try using a different X11 server or client. There are several alternative X11 implementations available, such as Xming or Cygwin/X.

If none of these solutions work, you may need to consult the documentation or support resources for your specific SSH server and operating system.
