The error seems that the host your are trying to connect to is unreachable.
You should try/catch your inside loop call to ssh.connect(...)
for this kind of error.

Many python libraries do through Exception in "exceptionnal" conditions,
SSHClient.connect do so as well:

If you want to make your code robust you should include exception handling.
