I used ssh to connect to my university's PC a couple of times. I can't do this anymore, it says port 22 timed out. The thing is I also tried other computers connected to the same network of the house, and the same happened.
But when I tried to connect with my phone with 3g internet, via a terminal application, the connection was successful.
So it's specifically the house's internet problem.
How can I proceed to resolve this issue?
