Are you using Vuforia Studio trial version? If yes, you can find the experience service URL under the Setting.
The default experience service URL should be available in the dropdown list.
Hope this helps.
its not for trail version i am trying to install license vuforia.
but while entering the usn & psw its showing wrong.
@thrinath For Trail, you can get the ES URL as shown above by login to Studio application settings. However, for commercial license PTC hosted you get the ES & login details via email by provisioning team.
Did you receive the email from the PTC cloud Provisioning team?
