Fixed it... IPV6 firewall was not port-forwarded, while the IPV4 firewall was. T-mobile LTE is IPV6 only and would only try to connect through IPV6.

I followed the instructions, but am having a problem. I can't login to bitwarden from the android app when connected to LTE. I can only login to the android app when connected to my LAN/WiFi. I can login to the Bitwarden webUI/vault from a web browser on my PC and android phone (on WiFi and LTE), I can login with a browser extension from a PC on the same LAN. Any ideas? I assume it is something with the certificates? I don't think it is port forwarding as I port forwarded port 443 and even tried to DMZ briefly to see if the firewall was the problem.
