i have the problem, that if I try to upload, for example, a picture to a document opened in Collabora Online I get the error showing up in a pop-up
Uploading file to server failed with status: 400. I can upload files directly to the NextCloud server over the app, webdav and the webpage and then add this to a document.
I am running the built-in Code Server for Collabora and have my NextCloud running with a Apache web server with the NC files in the root and behind a Nginx reverse proxy. Everything is running over https, the connection to the reverse proxy and also the connection from the reverse proxy to my web server for the NC.
I can’t find any related errors in the logs of the nc and the browser just says
POST https://[MYDOMAIN.EXAMPLE]/apps/richdocumentscode/proxy.php?req=/cool/https%[i guess unimportend stuff]&compat=/ws 400.
I hope anybody has an idea how this could be fixed.
Thanks for reading.
