Collabora inside docker seems to connect but is Initializing forever

I am new here so please point me to the right place for this sort of question if I am in error posting.

Ubuntu 22
docker run -t -d -p -e ‘domain=great\.domain\.net’ --restart always --cap-add MKNOD collabora/code

Owncloud is running perfectly. I can create documents for Collabora but when I click to open one I get this image forever:


Collabora Online Development Edition (CODE), Initializing…

I got it working - sort of. In my docker start string I changed it from: -p to --net=host and it immediately worked. However - now when I open any document I see restricted to watermarks all across every page. Are the watermarks related somehow? How can I get rid of these?
