Can't login to ESMC console

[hkrennrich.coreto 0]

I installed ESET Security Management Center Server as an VA under Hyper-V and fully configured it for our purposes.
But, however, i can only login to the webinterface.
Trying to login to the VA console allways results in "Authentication failed".

Shouldn't it be the same password?
I can't remember giving it a different Password when clicking through the first configuration.

I think i had to upgrade from 6.5 to 7 after the Installation.
Server Version: 7.0.471.0
Agent Version: 7.1.367.0
Server 2019 Standard with Hyper-V role
