Jellyfin app can't access remote server

If your friend is not in China, I wonder if this has anything to do with China's infamous "Great Firewall" that I have heard about, which means the government controls everything going in and out of the country and does not allow people inside the country to access anything outside that the government has not put on its whitelist.

I don't know for a fact whether it would block your media streaming server, but that seems to fit the profile for not officially approved connections.
