Dendrite port 8448 not listening

Background information

• using latest tag from docker hub:
• Postgres?:
• Running in Kubernetes:
• go version:
• Client used (if applicable):

Description

Federation tester does not seem to work and federation does not work. It looks like 8448 is not listening at all inside the container so the tester always fails. I can log into the server itself via Element after I create my admin user but Federated services do not work.
Of course I could be misconfiguring something as I'm new to matrix.

Steps to reproduce

1. run the docker image with kubernetes
2. point ingress-nginx to 8008 for TLS + webui
3. run federation tester and it fails.

Got this working by ultimately using a SRV record address pointing to port 443. 8448 seems to be a non issue.
