Github - cannot connect via ssh from time to time

Question

Situation

I use linux (mint mate 17.2), when I click on github via ssh, the connection does not work from time to time, it usually resumes after the computer and the network reboot. In a few days, it can become bad again, rather confusing.

Push via http never has such a problem, but it requires a password that is not convenient.

Debug Information

When pressed via ssh:

debug1: connect to github.com [192.30.252.129] port 22.

It is stuck on the specified line.

Then after a long wait, get a timeout:

debug1: connection to address 192.30.252.129 port 22: connection timeout

ssh: connection to github.com host port 22: connection timeout

fatal: Failed to read from remote repository.
