Keeping this connection alive is a bit of headache sometimes. Sometimes from server side, may be ssh server configuration or firewalls create issues and sometime from client side.

To avoid this issue you can you can adjust your SSH client’s or server settings.

SSH Server Setting to fix the issue -

# Open the /etc/ssh/sshd_conf on your server and update

SSH Client Settings to fix the issue -

Open PuTTY and update

Connection -> Category -> Connection -> Sending of null packets to keep session active -> Seconds between keepalives -> Type suitable value.

With this configuration, PuTTY sends a packet to the server every interval of time to keep the connection alive.

Or

# Update ssh_config

Happy Connecting !
