I am not able to access the zonedirector 1000 via browser, it is only in that screen below. Freezes on this screen and does not open the manager, I've tried in other browsers and also other machines, it's the same thing.
Have you tried a power cycle? Does it still answer ping, but not HTTPS? Have you saved a backup configuration since your last changes? You may need to try a factor default (indented button on front) for 8+ seconds, and see if you can reach it at 192.168.0.2 or not. If so, restore your backup.
If not, the light bulb in my living room that I never turn off, went out last night. =:^(
