Can't login to M4300 since 12.0.19.15 firmware update
Hello,
I just updated two switches M4300-28-POE+ to 12.0.19.15.
I go to the IP address of the switch
It has the AV UI login and the Main UI Login -
I can log into the AV UI login but NOT the Main UI login which is the one I need.
It goes to this site can't be reached. I reload no luck. I rebooted the switches - no luck. I tried another browser - no luck. I tried incognito mode, no luck.
There is no firewall or antivirus blocking it. It worked fine until the firmware update.
Short of resetting the switch to factory defaults which probably won't fix it, any suggestions other than applying an older firmware?

Found the issue - for some reason when you click on the login it brings you to http://IP-Address:49151/v1/base/cheetah_login.html instead of http://IP-Address:49151/v1/base/cheetah_login.html
