I installed Nethserver on my dell optiplex and I setup everything correctly and I just setup Active Directory and it seemed to work but when I added a new user it stuck on the loading screen and then I refreshed it and was brought to this screen.
I also ran the config show nsdc command and it returned this.
nsdc=service
IpAddress=192.168.0.204
ProvisionType=newdomain
bridge=br0
status=enabled
