Description of my problem
[Nextcloud Hub 3 (25.0.4) – Nextcloud Office - Could not connect to the Collabora Online Server

Error message
If I call this URL:
"https://my-Server/browser/dist/admin/admin.html"

then this error message appears:

"502 Bad Gateway
If you see this page, your connection with the server is working but the internal service providing this path is not responding.
Administrator, make sure that the service is running, and check its logs if it is not. The Services page is in your webadmin, under Tools > Services."

The coolwsd service is started.

All logs show no errors.

Best regards

I had a similar issue. Just rebooted machine then logged out from all logged in users (i mean logging out from yunohost user panel). That worked for me. Also after connecting and setting up Collabora Online Server, if i login to yunohost user panel again server is being unreachable. Could you verify these? (or maybe i misconfigured something 🤔 )
