VSA Manager Failed login due to bad username and password

Issue: VSA ovf has been imported and in the VSA appliance the user has logged in but during the windows installation of VSA manager it throws an error saying
"failed login due to a bad username or password" without asking for any username or password.
Workaround: Login with a local admin account and proceed with the installation.
