I too had the issue where I could log in externally with the browser, but not the app. I had me running in circles for days!

With me the issue was resolved when I turned off the IPV6 flag for my domain (that is, where my actual domain is registered, with Dynu).

Turns out that the app was trying to resolve my IP for jellyfin.domain.com through IPV6, where I didn't actually have that available on the IP where it pointed to. So turning that off resolved it for me. Looks like a browser is clever enough to just try IPV4 if IPV6 doesn't work, whereas the app will just slap you in the face.

I did not have the computer machine firewall open for IPv6 though I had everything else correct.
