Failed to load Nextcloud Office


im running Nextcloud 24.0.4.
I went trough this guide:

to install/integrate Collabora on Nextcloud. For now everything is set up and works until i want to open a document. I get the error Message “Failed to load Nextcloud Office - please try again later”

I tried many things i found here but nothing has worked for me.
Any ideas?
