Cannot log in my nextcloudpi

Hello support,

i cant login to my nextcloudpi. I cant connect to the server.
Had anybody an idea what i can do? :frowning:

Some more information would be helpful. Was it working before and quit, or has never worked, have you checked that it’s running, etc…

I installed Nexctloud with Nextcloudpi from “Own your Bits”. The Config Panel worked many days. Some days later i enabled ssh access and i used these commands:

sudo shutdown
sudo reboot
sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoclean
sudo apt-get clean

i also installed these apps on my phone:
RasPI check

I didnt do more

“This website cannot be reached”

i can log in to my Nextcloud, but not to the Config Panel. Everything works except this access
