This is so sad, it makes me cry a lot 😂😂

Every of your links is about the webmail app not nextcloud as a whole

Ah right, sorry; the company doesn’t support it directly but the docs provide an example. To me as tinkerer that was solid enough 😂😅

Nginx is supported and a good choice. What database are you using? I’d recommend MariaDB.

I am using headscale without any issues

I have found some proxy states useful as well, good idea to make them „house states“
