Here is someone else who has the same problem.
Failed to convert preview: Client error: POST https://XXXXXXX.de/apps/richdocumentscode/proxy.php?req=/cool/convert-to/png resulted in a 403 Forbidden response
Could it be that Nextcloud Office or the Collabora Code Build-In Server has a bug here since the last version? I didn’t have that before either.

I have a similar problem. I get, CURL 28 and 502 errors at /cool/convert-to/png and hosting/capabilities.

I’ve been playing with the reverse proxy and DNS but haven’t found any solution yet.
Same problem here.
Just updated to Nextcloud 30 (Docker setup, with nginx as a reverse proxy, everything up to date). It had been working just fine previously, and I’ve gone through several Nextcloud upgrades.
curl https://cloud.alchimie-web.com/custom_apps/richdocumentscode/proxy.php?status
says {"status":"OK"} (either from a browser or from my Nextcloud container)
so I assume it’s a bug in the last update
It really seems to fail (http 400) at fetching proxy.php?req=/cool/convert-to/png
