Account authentication failed (Csharp)


Account authentication failed (Csharp)

I have a legacy integration that works for some clients but not all clients.  This one client recently changed their password and we are now receiving a ConstantContactUtility.ConstantAuthenticationException Message "Account authentication failed"


Client has verified that the username and password is valid as they are able to log into constant contact with these credentials.


Other clients running the same software build are able to authenticate.
