connection timed out

[matiasandina]

After a while, for reasons I don't understand, ssh connection gets timed out On bash, while running, get these messages

ssh: connect to host choilab_ip port 22: Connection timed out
lost connection

If open another terminal on Raspberry and do ssh choilab@choilab_ip, connection gets re-established

Also, not supper reproducible (?). Did not happen in other times the script ran for long

ssh connection timeout occurred for different reasons:

• machines are unplugged
• machines have no internet access
• there might be problems with the fingerprint and ssh keys
