Why can't I connect to ssh from Linux?

Question

SSH

There was a problem, it is not possible to connect to the ssh server from Linux. Tried from the phone and Windows - everything is fine.
With -vvv the output is:

Connection to XXX. XXX.XXX.XXX timed out while waiting to read

Answer 1

Falls off on a timeout. In /etc/ssh/ssh_config add the line serverAliveInterval 50
