I've been pulling out my hair trying to set up communication between dockers with hostnames instead of IP-adresses.

I've been reading everywhere that it's recommended and I surely understands why, but nowhere is there a guide?

I've gotten the hostnames with docker ps command, is the names listed there also what they call themself internally?

The dockers are running on the same custom docker network.

I have connection between them if I specify IP.

I've added the network (172.18.0.0/16) to allowed hosts/trusted networks in the dockers Web UI.

What I'm i missing?

EDIT: I had to add the dockers hostname to allowed host. Aka, in radarr, add binhex-radarr to allowed hosts (if using the binhex docker ofcourse)
