SOLVED: Access via local domain works in browser but not app

[lkadin]

If you are using https with self-signed certs, a lot of our apps will fail to connect.  Unless you add your cert to the OS's trust store.  If these will be local only connections, why bother with https?  Or caddy for that matter?

Do you intend to setup remote access via Caddy at a later time?

Caddy is simply in order to make more user friendly urls for all my services. Both for me when I'm setting things up and trying to remember the port from one service to another, as well as others that will eventually access via the WireGuard VPN I have set up.

I understand that HTTPS could be problematic with the self-signed cert, but I also tried via http, I set caddy to serve http only, and the result was the same so I don't think it's currently a cert issue.

I have the same issue without using https or self cert. It just won't connect. I even loaded a browser app on the chromecast and that connected fine.
I saw some posts about possible IP4 vs IP6 addresses but that does not seem to be it. I also saw some posts about 5G wifi vs 2.4, but don't know how to check if that is an issue.
