Two simple possibilities:
Heroku is blocking on their (the server) side, not yours (the client).
The University is blocking outbound traffic on that port.
I suspect you can check and configure the first one; the second one you'd
need to inquire with your university's IT department.
You are using the same machine at home and at the university? If so that
should preclude it being your machine (though its possible your firewall
has different settings when connected to the different wifi networks).
Online port checkers are prone to false negatives.
