I have a very strange problem:
I have a multi-tenant host where some days ago I added a tenant listening at
Everything went fine until I wanted to change it to
Accessing this domain just kills the application pool:
Zusatzinformation 1: 660a
Zusatzinformation 2: 660a0a858c669b5babba54a1588eca77
Zusatzinformation 3: c92d
Zusatzinformation 4: c92d0a00d464aeff687ce5c872da70be
I can change the domain to whatever I want:
Everything works but not the domain I want "dev.example.org"
But now the really strange thing about this:
I can create a new tenant which receives "dev.example.org" and it works!
And even more scary:
Some days ago the tenant had a different host (test.example.org) and we wanted to change it to "www2.example.org" which also killed the apppool when being accessed -- so we changed it to the now existing "development.example.org". Of course
"www2.example.org" works today; but today I don't need it anymore -- I definitely need "dev." now, but thats the only one of 1001 possibilities which doesn't work.
