Users can't login

Hello all. I’ve seen truenas many years ago. Now i have installed Truenas Core on a Dell server T620.
I can acces Truenas via dhcp. But I also configured a static ip. Saved, but after a reboot i can no longer login via the static ip. It seems it’s not holding the information (and yes i am quite sure i clicked “save”.
Also i made a user “admin”.gave it a password. and once again click save. But i can’t login with that account. Password seems to be incorrect. I only can use root to login. Is this normal behaviour ?

There’s also a problem with igbo. My first ethernet adpter. Ater a Truenas reboot i seen on the console: the web access can not be accessed. The web user interface is at ip address 0.0.0.0 ? what does this mean ???

For CORE, yes. The only user that can log in to the web GUI is root.

iX has been recommending SCALE for new deployments for over a year now; CORE is all but EOL.

Ah ok. then i shall not put more work and effort in this version. I will look to Truenas scale thanx
