I assume Collabora does not work at all? It's not just these errors you're seeing, correct?

Did you initially activate from the web UI or was it via occ?

Your config indicates:

            "wopi_url": "https:\/\/cloud.orangekarat.com\/apps\/richdocumentscode\/proxy.php?req="

But the log says it's using localhost as well as http so something is wrong here.

Does the problem go away when you either toggle in the Web UI between Use own Server and back to Use built-in (or run occ richdocuments:activate-config from the command-line)?

If none of that works:

• what version of Server did you upgrade from when this started?
• what memcache are you using?
• share the output of occ config:list system

Colabora was activated via the webui and it's working well. I'm able to successfully load and edit documents with Nextcloud office. I only noticed this problem because I received a warning in the admin panel that several thousands of errors were in the log.

I have not made any changes to the default configuration of Nextcloud Office since I installed it. When navigate to the Office admin settings, this is what is reported:

I upgraded Nextcloud server 28.0.2 from that last incremental release of 27. I try to keep my instance as up to date as possible.

I'm using redis for memcache

And here is the output of occ config:list system

    `"overwrite.cli.url": "http:\/\/localhost",`

Is there a reason you're using http://localhost in your overwrite here?

As far as I know that was set up automatically, and I must confess I don't even know what that setting does. I have only made a few modifications to the configuration apart from using the webui (like for setting up the redis cache).

[joshtrichards]

It's possible it was set if you initially installed via http://localhost.

It should be the full URL used to access your Nextcloud Server instance. So it sounds like you should change it to https://cloud.orangekarat.com in your case. Then restart your web (if using mod_php) or fpm (if using) service. Then see if your problem goes away.

I will make that change and will see if that clears the issue!

[unknownuserisknown]

I made the change and re-enabled richdocuments and Colabra. After about 30 minutes or so no of monitoring, I see no new errors in the log. Thank you for your help!
