I installed nextcloud a few hours ago on my own vserver, which I rented by a german hoster.
First of all I have to say, that english is not my native language and I know not too much about linux.
These are my system informations:
2 GB RAM
300 GB SSD
Linux: Ubuntu 16.04 .1 LTS
Device: ASUS ZenFone2
This problem occurs when I try to connect to my nextcloud server from my Android device.
I enter my domain, user and password and get the following message.
All the other stuff on my nextcloud server runs fine.
If there are any needed informations I post it.
