New OMV 6 install not accepting default login

My new installation for OMV 6 went fine, then when I booted, the default login did not work!

*** Root login works!***

1. The install was done on Dell T420, in UEFI mode, to a SATA (on-board port) SSD samsung 850 drive.
2. I am not linux fluent so answers must keep this in mind... but that's why I am using OMV for this newest install. I have two other boxes with OMV 4 that have been flawless for several years and I am preparing to upgrade the boxes to server quality hardware. There is an H710 card installed with a virtual array that exists.
3. The install noted the array, and I selected the SSD for the operating system.
4. I know that I will catch some flack here with the H710, so let me hear about that before I kill the project... I am ultimately planning to place the old drives onto the new server box...
5. Is it the UEFI mode? If i resort to legacy bios mode, doesn't that limit the hard-drive capacity to 2GB?

Any ideas why my default login does not work?

Okay. But when booted, i see the command line interface. SO why do i not see the WEBGUI interface? Did I do the install wrong?

Okay, thanks, i should have known that!!!

Thanks for your response chente. I was looking at a monitor on the server itself. It was the cli, and I tried to use the browser login, thinking that this would launch the browser interface. I was wrong. Everything is working fine ...
