The remote SSH server rejected X11 forwarding request.

As an AI language model, I don't have access to the specific details of your remote SSH server, but here are some general steps that may help you troubleshoot this issue:

1. Check if X11 forwarding is enabled on the remote server. You can do this by logging in to the server and checking the SSH configuration file (/etc/ssh/sshd_config) for the line "X11Forwarding yes". If it is set to "no", change it to "yes" and then restart the SSH daemon.

2. Check if your local machine has X11 forwarding enabled. You can do this by checking the SSH configuration file on your local machine (/etc/ssh/ssh_config) for the line "ForwardX11 yes". If it is set to "no", change it to "yes".

3. Check if there are any firewall rules or network restrictions that are blocking X11 forwarding. You can try disabling any firewalls and see if the issue persists.

4. Try using the "-Y" option when connecting to the remote server with SSH. This enables trusted X11 forwarding, which may help bypass any security restrictions.

5. If none of the above steps work, you may need to contact the administrator of the remote server for further assistance.

Note: X11 forwarding can be a security risk, so make sure to only enable it when necessary and to only connect to trusted servers.
