AIO Talk as standalone container on different server

Hello everyone,
I’m having problems installing the Talk container (image: nextcloud/aio-talk:latest) on a different server than the other container instances.

When I use the command curl -i, I always get an error. Alternately 404, 501 or 502.

Thank you for your help :slight_smile:
