Cannot log in ADNM Error 0x7FFF3004

I am not 100% sure this is the right password to log into our Avast Distributed Network Manager Console, but I have tried several password that we normally use and every time I get this message

“The server certificate does not seem to be valid!
Either it has an invalid signature or it is expired.”

I can click OK and then I see this

Error 0x7FFF3004
Unable to login as administrator or connection error

Help? :frowning:
