I have the same or similar problem!
We worked on 1.05 with our config. But several days ago i decide to upgrade firmware to 02.12. After ftfp upload the switch was rebooted and web-interface wouldn't respond but i can stil ping my old ip. There is open ports 80,161,443 on old ip in nmap scan i see, but no luck with connect.
We decide to reset the switch, but it couldnt reset config. After reboot it stil has old ip and i can't connect on web.
I found that since 02.12 there must be password for "admin". Could it be the reason?
Here my simple config
