Setting up an XMPP-Matrix bridge

[Eirikr70]

Hello,
I run a Docker-ECS XMPP setup that works fine. I am trying to set up a bridge with Matrix. I have followed this blog post, and that step is ok. I have declared SRV directives ... But the federation tester shows Get "https://xx.xx.xx.xx:8448/_matrix/key/v2/server": dial tcp xx.xx.xx.xx:8448: connect: connection refused.
I suppose I have further steps to go but I don't know which. Could someone show me the way ?
My docker-compose.yaml

Sorry, I just hadn't mapped port 8448 in the docker-compose.yml. My bad !
