#`Server is not reachable` error on Immich iOS app when using custom domain, but works using local IP

On my brother's iOS app, if he uses the local IP address in the iOS app (http:192.168.1.101:2283), then he gets the prompt to enter his username and password

but if he uses my custom domain with the subdomain (https://abc.xyz.com) which my AdGuard Home is using DNS rewrites to redirect the traffic back to my home server's local IP address's reverse proxy (Caddy) to the Immich, then it is giving the Server is not reachable error. This is also weird because every other iOS and Android device in my home is able to connect using the custom domain name to the server both in our local network and remotely too.

What's going on specifically with my brother's Immich app?

It should also be noted that I'm able to see Immich on my brother's Safari app on his phone using the custom domain https://abc.xyz.com.

His phone is not using your DNS server

Oh I didn’t see that. Try rebooting the phone. Also share screenshots of the exact url you’re entering in both

Any chance we can do this without sharing exact URLs? For security reasons, I'd prefer not to write out my domain name. If it helps, I can use the exact domain name that is following the format: https://subdomain.domainname.com, and it works perfectly fine if I'm on data on my brother's phone, but as soon as I switch to wifi, it gives me the server is not reachable error.

I also tried restarting his phone, but no good.

The closest GitHub issue I could find that was somewhat maybe relevant was this one... https://github.com/immich-app/immich/discussions/22316

I also just tried it with my brother's iPad. Same URL and everything, and it worked as expected. Checked the WiFi settings and they're both hooked up to my local DNS servers.

The only thing I can thing of is that I initially had setup my brother's app on his iPhone when we were outside the network (not in the home network), so he only saw connectivity issues when he came back into the home network, whereas for every other iOS device for my family, I had configured it INSIDE the home network.

I really don't know what difference this could make, but it's the only difference I can think of right now. I'm guessing whatever it is, it's a configuration issue that's somehow cached even between uninstalls and restarts of my brother's device. I'm going to uninstall the immich app entirely from his phone, and then wait several days if need be to ensure whatever's going on goes away or something
