Has anyone seen this issue before?

Moved to new hardware for COnfigMgr - same name, new OS (Server 2012 R2) and App Portal cant insert machines... I suspect I am missing something in IIS on the new hardware, but, to me, it looks right. But thats a lack of sleep and too many Monsters.


(i have a case open with Flexera, but its Sunday so... yah know, this was worth a shot)
