@TimBr Did you migrate this from an older server?

The getPrimaryGroup/getStorageGroup’s are the indicator of the problem here.

Basically, you would likely see the same type of problem if you were to goto snapins:

Effectively the issue is the Image (in this instance) is associated to a StorageGroup that simply doesn’t exist or that storage group has no storage nodes associated to it.

@TimBr Please explain more presicely where you get the login failure and where it does work. Best if you take a picture or video. As well let us know about customizations on your FOG server and the version you run.

I am asking because neither a normal deploy nor debug need a login in general. So we need to know more to be able to help.
