Hello Guys,
I am trying to set Alternate Login method/ID in Azure AD connect, so trying to connect Azure AD but while connecting its throwing error
"Unable to validate credentials, An unexpected error occurred. The underlying connection was closed. An unexpected error occurred on a receive"
Not sure the cause, Can anyone suggest the way out.
We are using Azure AD connect Basic version and there is no issue on syncing the objects and password.
Any assistance is highly appreciated.

Thanks
