Android App can't connect to reverse proxy but can with public IP/port

Troubleshooting
1

In the Android app, I can’t connect to the server with my reverse proxy URL (https://chat.example.com) but I can connect with my public IP and port (1.2.3.4:8065). All I get in the error message is a basic “Can’t connect to this server”. Nothing shows up in the server logs.

I can easily connect to the server with the reverse proxy on the Windows app and it works just fine in the browser.

Tried SSL Server test and got an A+. I’m using Let’s Encrypt.

Assuming that chat.example.com does resolve to 1.2.3.4, you’re connecting to port 8065 with no encryption with 1.2.3.4:8065 https://chat.example.com/ is trying to connect to port 443 with encryption. Two totally different animals :wink:
