Seafile server CE 13 - deployment error CSRF

When I follow the instructions for deploying seafile server 13 CE from Setup community edition - Seafile Admin Manual I encounter the following problem:

After a successful login I get an CSRF error page (django backend)
FIX: add to seahub_settings.py:
CSRF_TRUSTED_ORIGINS = ["``https://sub.domain.com``"]

This is something you may want to fix before releasing v13, or at least mention in the docs?

Normally you don’t need to add CSRF_TRUSTED_ORIGINS = ["``https://sub.domain.com``"] for a clean installation.

Did there anything special you do during the deployment?

Hi,

I’m using nginx outside of the docker containers, as a reverse proxy - don’t use caddy at all.

All per seafile documentation
