Remote access doesn't work, local access does

[RemoteUser1138]

After yet more troubleshooting, I think I figured it out. Maybe. Still needs testing.

The problem all along seems to have been with a commercial VPN application I was running on the host machine.

To be clear, this is used to access a commercial VPN service, this is not the same as the VPN server running on my router (which is used to allow remote clients secure "phone home" ability). I did not think to mention it before, because it did not occur to me (or anyone else, apparently) as relevant.

That commercial VPN application has a feature to allow access to local subnets (outside the VPN pipe, if you will) while connected to the VPN, but it's buggy.

Once I disconnected from the commercial VPN service, remote clients (using the Ubiquiti VPN server) were able to access Jellyfin again.

I don't always have the Jellyfin host machine connected to the commercial VPN. I believe that the seemingly-random periods of Jellyfin access working or not, mentioned above, were exactly those periods.

I'll do more testing and post a follow-up in a week or two.

The VPN provider's docs state that you can add a static route to your machine to work around the subnet problem I mentioned.

I will be adding a persistent static route. I need to have the Jellyfin host machine connected to the commercial VPN service most of the time for reasons. Will test that setup and report back.
