[SOLVED] replaced router (for another reason) and new model works fine somehow

Hey guys, my Firefox on Android cant open selfhosted services using DNS host names on home wifi.

I moved to a new place, got new router, configured server with new local IP. On PC everything works fine, but on Android Firefox I get "Address Not Found" when I try to open local hostname. Using IP:port works, but its been working fine before we moved. Chrome on Android works fine, desktop PC works fine.

Im running pihole and nginx proxy manager on server (I reconfigured pihole, but settings should be the same as before). I have set server IP in router DNS settings. I have set static IP for wifi network on phone and DNS address of server (I think I didnt need this before, but now it doesnt work in chrome without it). I have 2nd pihole on rpi4 as secondary DNS server on both router and phone settings, but its not in use yet. When I reconnect to wifi firefox can open the page for like first 20 sec and then it stopps working.

What am I doing wrong? Ive been using firefox on android exclusively before we moved

Check your Android's DNS settings. After that grab a tool like net-tools and see if you can resolve it from there.

After selecting home wifi ssid settings I changed from dhcp to static and set static IP and DNS (my server with pihole + another IP thats not in use yet). In wifi settings under DNS I can see both IP adress that Ive set, but I also see 3rd one that starts like IPV6 address from About Phone section.

Private DNS is off. Is there anything else? Im using Android 12 on Motorola Moto G42 (not rooted).

I got app called Net Tools from play store and I cant ping hostname (Unable to resolve). Pinging local IP works and I can scan opened ports, but cant ping https://192.168.100.40:3300

What can I do? Stupid chrome is working fine...

Im not sure what you mean. Example is https://jellyfin.tride

Im using self signed certificates if that matters. I used to get certificate warning just like I get in chrome now
