Thanks for trying out Mayan.
Changes to allowed hosts and other variables were only when people were upgrading from 3.2.x to 3.3.x. if this is a clean install it doesn't apply to you.
We really need the logs of those workers.
Inside /var/log/supervisor there should be files like "mayan-worker-slow-xxxxx". We need the logs from those files to see what error Celery is having (or output from docker logs <containername>)
I have a strong feeling we're either going to see "unable to connect to amqp" errors or unable to connect to the database errors in the worker logs.
Can you paste your supervisor config for me please? (/etc/supervisor/conf.d/mayan.conf). I assume you've installed into /opt/mayan-edms/ if you're doing a direct install?
What operating system are you running on? Is this a direct install or docker install?
Sorry about the questions but answering all the above should give me everything I need to get it sorted in one go
That allowed hosts entry looks normal to me.
In terms of behind nginx, what error are you getting? - Ultimately though your mayan install isn't currently working because the task queues aren't starting. Without those workers running document uploads won't work (and 90% of the rest of Mayan functionality won't work even though the web UI looks like it does work).
Side note: we have the traefik tutorial at viewtopic.php?f=15&t=1563
so I know reverse proxying works.
