ssh server connect to host xxx port 22: Connection timed out on linux-ubuntu

Question

I am trying to connect to remote server via ssh but getting connection timeout.

I ran the following command

ssh testkamer@test.dommainname.com

Answer 1

There can be many possible reasons for this failure.

Some are listed above. I faced the same issue, it is very hard to find the root cause of the failure.

I will recommend you to check the session timeout for shh from ssh_config file. Try to increase the session timeout and see if it fails again
