I have one other _speculation_ based on all the other urls explaining what "Network Error:...". The reason the University could "get a message" through your firewall is that your session did not or the server did not cleanly disconnect you the other night. Finally either the sys admin or the sshd daemon on the University computer disconnected you. Hence the "Network Error: Connection Reset By Peer".
