It's a Let's Encrypt certificate.
And this shows everything is secure.
Yes, this happens, when I add my server to a system account.
I tested yesterday on my tablet too - so this happens my both devices.
My tablet was connected to this server and it worked.
But now it shows the same error.

Hello,
sorry, my first post here.
Thanks for moving the thread.
Seems that there is a problem with login to Nextcloud.
If I use https:// at server data, than no login is possible (test says "offline" and no news sync works).
If I use the server without https:// login is possible (test calls "online"), but news sync isn't working too.
Some weeks ago, that worked at my configuration. But I had to reinstall the OS, and now there no News on my phone.
