SOLVED: Android app goes to "choose server" when leaving home WiFi

[TheDreadPirate]

When I am leaving for work in the morning (or any time I leave my home), if I start playing music via Jellyfin on my android phone while I am still on WiFi when it does switch over to cellular the Jellyfin app immediately drops me back to the "choose server" login screen and makes no apparent effort to switch/reestablish a connection via cellular.

My phone is configured to use my DDNS address and my router (Netgear R7000 running Fresh Tomato) is configured for NAT loopback so that those DDNS requests still appear as LAN accesses to Jellyfin when I am at home.  This way I can direct stream while at home and transcode while not at home without having to switch addresses.

My workaround is to wait until I am out of WiFi range to open Jellyfin and start the music.  But I'd rather not be fiddling with my phone while driving.  Is this something I can address with a router or Jellyfin configuration change?  Or is this an unintended app/server behavior that I should submit a bug report/feature request for?  I imagine that this has something to do with the stream switching from my home WAN IP to my cellular IP mid-stream.  And my music playback settings differing between LAN and external accesses (transcode to 128Kbps when accessing from Internet).

Jellyfin 10.8.10 native behind Apache reverse proxy on Ubuntu 22.04 LTS bare metal.

i had this exact issue and ended up switching the default player which allows more "buffer time" and doesn't immediately drop.

Jellyfin app > Settings> Client settings> Video Player Type > Integrated Player

havent had the issue since moving to integrated player.

Well the issue is that the connection is aborted from the view of the app and the "route" is no longer available. So from the apps perspective its a reasonable thing to do.

The whole issue goes deep into the topic what for example HTTP3/QIC does better, HTTP3/QIC does support such kinds of changes in network with a single connection but until we build upon that, its the "standard" why of doing things i would say.

I just crash the app and reopen it.

It's annoying it happens to me even if I drop wifi for a few seconds while walking through a dead zone in my house.

Edit - going to try internal player as a user above suggested. Will report back
