Can't use collabora with Nextcloud

Hi, i followed Integrate Collabora Online with Nextcloud on Ubuntu with Docker and each time i try to open a document i get error in nginx and nextcloud

nginx error:

2022/02/15 08:43:35 [error] 2335951#2335951: *23 open() "/usr/share/nginx/html/browser/739da71/cool.html" failed (2: No such file or directory), client: x.x.x.x, server:, request: "POST /browser/739da71/cool.html? HTTP/2.0", host: ""

Hello, I also was failing with the docker installation, so I installed it the “classic” way, which is in fact more simple.
Follow the guide until you have a working Nextcloud environment, then switch to this one to install Collabora online/Onlyoffice to your Nextcloud instance:

damn 2 months later :joy: but hey at least you replied so thanks

about that thought onlyoffice sucks as it does not support RTL languages (aka Arabic) so I installed collabora (which had it’s own problems too for example dev changed lool direction in server configuration to cool and it took me days to figure it out)
