Why am I getting an error that says "unable to establish connection: please verify your credentials and try again later" when switching Avatax Usernames that are plugged into my Zuora Integration?


You want to know why you are getting an  error message when switching Avatax usernames that are plugged into your Zuora Integration.




  • If you update the Avatax username that is plugged into your Zuora integration, you also need to reenter the License key for that environment. If you do not, the test connection will not be successful.
