Nextcloud/Collabora docker-compose help

ℹ️ Support 📄 Collabora

I’m able to get Nextcloud working with the docker-compose settings below. I have then tried to add a Collabora container. The container is up and running, but I can’t edit docs inside Nextcloud, I just get a blank screen.
Can someone kindly offer any assistance?

It seems I have solved the issue.
Originally, I had tried to insert the reverse proxy code into /proxy/conf.d/default.conf, but the file would reset and not keep any changes after a restart.

Instead, I just made a new file named /proxy/conf.d/domain.conf, and pasted the reverse proxy code from icewind.nl, now it all works.
