3800 series Web GUI times out

[DoublePositive]

I am having some trouble with the web interface for my new E3800 (3800-48G-4SFP+ Switch (J9576A)). I have two of them stacked in a ring topology. When I restore to the factory default and add an IP address for my LAN to the DEFAULT_VLAN. I can connect and it works. Then after a bit of customizing the web interface stops working. I can't figure out why. My running-config is below. As you can see, I don't have any of the ports in the "back" VLAN. Any ideas?

I found the answer!! I was configuring the OOBM interface which must automatically turn off the WebGui through the a VLAN. I needed to do the following;

disable the OOBM

enable "management-vlan 1"

Make my ip an authorized manager

Commands: (once in the config context)

oobm disable

management-vlan 1

ip authorized-managers myIP
