Can't Connect to Mailcow UI with FAQN

Noobie

Hi,

I’ve been trying to use Mailcow with docker compose, but have had issues setting it up to work outside of my LAN. If my hostname is mail.example.com, I can’t connect to https://mail.example.com. However, I can connect to https://192.xxx.x.xxx. (All the X’s are the rest of my local IP address). In every tutorial, people seem to be able to connect with their FAQN, meanwhile I can only connect with the local IP address.

Any help is greatly appreciated. Sorry for the lack of logs or details as I’m not sure what exactly to provide.

192.168.0.0/16 is a private IP range. You must use a public IP address outside your LAN and set your DNS records accordingly.
