I installed the newest version of collabora office - 18.104.22.168-48.
It is installed on a separate Ubuntu 20.04 LXC privileged container using official docs and then connected to nextcloud v21 via reverse proxy.
I have another LXC container with Ubuntu 16.04, 22.214.171.124-41 version of collabora and the same config on reverse proxy - it works, but with Ubuntu 20.04 toolbars are not showing up (it shows for about a second and then dissappears).
I tried to use both classic and notebookbar, both doesn’t work.
No errors in loolwsd logs and in developer tools.
Did anyone have similar issues?
Would be grateful for any help
