Other valuable info

The documentation says
add all [Cloudflare IP-ranges](https://www.cloudflare.com/ips/) to the wopi-allowlist in https://yourdomain.com/settings/admin/richdocuments

but I do not know where I can find settings/admin/richdocuments

[MarcS1975]

Found the solution:
The wopi-allowlist can be accessed within Nextcloud via Administration Settings - Office - Advanced Settings
Allow list for WOPI requests
You can add the Cloudflare IP ranges there, update the settings and restart the Collabra container.

I followed these instructions (i.e. the ones on the reverse proxy readme), added all the IP masks from that list and any I could think of, but WOPI still doesn't work (vs empty WOPI or something like 255.0.0.0/1 does, so the issue is with the addresses). Is there a way in AIO to debug which IP is actually failing? I guess Collabora logs could be set to a more verbose level, but that's not straightforward within AIO.

Is it really necessary to restart the container? Changes in the UI seemed to have an immediate effect even without that.

Edit: right after I wrote this, I found this discussion about debugging code: #1358 . It seems the answer I'm looking for is there.
