I always seem to get issues opening iManager from various machines.
Sometimes it doesn't open, but recently I get the following:

https://192.168.0.1:2200
This takes me to a login screen. https://192.168.0.1:2200/welcome/loginpage
I put the password in and it then opens up,

https://192.168.0.1:2200/welcome/index.html

which is just an information type of screen. If I click on iManager on the
left pane, I simply get an information screen about iManager. A while ago I
created some shortcuts which took me straight to iManager and I was then
able to log in and manage etc. For some reason, I now get the above using
the same shortcuts.

Cheers all.
