I've set up my homeserver via matrix-docker-ansible-deploy, but made the mistake of using my domain as ansible_host variable at first. I think that is why now my Coturn server doesn't work as intended. Calls can only be made (in Element) when I enable turn.matrix.org as an alternative in the settings.

Since the initital setup, I've correctly replaced the domain with the server IP in the ansible inventory file and reran just setup-all, but I still can't make calls via my homeserver.

1. Is it likely that the mistake I made is causing this issue?
2. What can I do to correct the Coturn configuration or otherwise fix this issue?

EDIT:
I've found this in the docs: https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/docs/configuring-playbook-turn.md#manually-defining-your-public-ip
I'll try this and report back.

EDIT2: This did not fix the issue.
