I'm pretty sure he tried this by restarting his PC.

He hosts from home.

He can go to www.whatismyip.com (DONT publicly share the IP here though and be cautious who you share your IP with).

Default Valheim port is 2456 (if he has not changed that this'll work)

So to join you'd have to fill in his IP adress and add ":2456" to it. It'll look something like:
123.456.789:2456

Edit: Some interpunction added for readability :)
