Host Credentials Are Invalid



I am attempting to add my Logger to my Management Center via attempting to add a new host. I have checked the host name is correct and the same as the host name in the certificate. Both the username and the password are correct and this has been verrified by various members of staff.

The Issue:

I am getting the above error which is different to "Login Failure" which I receive when I enter spurious data into the password field.

Could someone please shed some light on to what this error actually means?

Thanks in advance
