Not able to save-as/convert files

[D592VN5]

Hi there,

Fresh installation on Ubuntu 22.04, php 8.3 in FastCGI mode, latest Nextcloud 31.02, Collabora Online 24.4.1302 (no upgrade history)

Running in build-in server mode.

All functionality seem to work as expected, except for Save-as operation (to pdf, for example) - this returns error.

richdocuments ClientExceptionClient error: POST https://test.com/apps/richdocumentscode/proxy.php?req=/cool/convert-to/pdf resulted in a 403 Forbidden responseFailed to convert preview: Client error: POST https://test.com/apps/richdocumentscode/proxy.php?req=/cool/convert-to/pdf resulted in a 403 Forbidden response

Checked for proper chown & chmod - seem not to be an issue
Allow list for WOPI requests is left empty for debugging
Also disabled cloudflare proxy - no effect

Running out of ideas...

Thank you.

Hi, I also have the same problem! Interestingly enough, it only appears when converting the file from the drop-down menu in the file browser. If I open the file in the editor and use Save-as from there, it converts and saves properly.
Have you maybe found the solution, by the way?
