I have tried helping him through Discord by the following command to check what processes/applications are using his port 80
and then checked the PID to get application name
Code:
tasklist /svc /FI "PID eq applicationpidnumberhere"
and disabled every application/process using his port 80, Still it cannot be reached, Although nothing is using port 80.
I assume it might be ISP blocking it or something I missed.
