When connecting to FastX, the initial connection succeeds, but when you try to connect to a session, you receive the error. “There was a problem connecting to the session”
Checking the details of the logs can provide more information. Here are several common causes
- SSH port forwarding is disabled.
In this case, the connection log will have a message like this:
Opening connection to 127.0.0.1:41120 for forwarding from 127.0.0.1:60178
Forwarded connection refused by server: Administratively prohibited [open failed]
This can be caused by having this line in /etc/ssh/sshd_config on the server:
- Session has died. (Xorg process has failed.)
In this case, the connection log will have a message like this
Forwarded connection refused by server: Connect failed [Connection refused]
Another possible log entry, instead of the “refused” error, is something like this:
Forwarded port closed due to local error: Network error: Software caused connection abort
- Windows Firewall is blocking localhost connections, or localhost is returning wrong IP address.
In this case, the connection log will not have the “Opening connection to 127.0.0.1:…” message.
