Describe your issue

I’m trying to have Nextcloud be accessible through https://nextcloud.xxxx.nohost.me, but since I restored a backup, it shows the “welcome to Nginx!” screen when I go to that url.

The url is set in the webUI on the subdomain, with no input after the slash, i.e.:
Move the app to a different URL
https:// nextcloud.xxxx.nohost.me / [empty]

The server itself, on https://nextcloud.xxxx.nohost.me/app/dashboard is reachable just fine.

Share relevant logs or error messages

I don’t have relevant logs, I think.

It worked fine on my phone, I figured. So I cleared my cookies and it worked. Oh well!

I had this prolem so many time this week, due to multiple failed upgrades (due to not yet upgraded apps).

After I disabled the apps, the upgrade went right and I do not have this message.
