Surprisingly, without any known changes, we suddenly receive a new error when establishing previously error free connections. The following error appears in the client, however the connection is established as usual without any problems.

So why does this annoying error message appear and how can it be fixed?

Connection failed. Cannot create remote file ~templatemate3/.x2go/ssh/key.TJ4977 - SCP: Warning: status code 1 received: scp: ~templatemate3/.x2go/ssh: No such file or directory

Thank you!
