| 5023 | Unable to communicate with the testing server. Please contact your administrator. | Contact your local system or network administrator; there was a parser error (bad data was sent from the application to the engine or from the engine to the server) during authentication.

| 5026 | Invalid login token. Please try again. | Logout and log back in. Autologin using an authentication token has failed because the token has expired or is otherwise invalid or not recognized. The authentication token is requested from TestNav by the customer site and must be used within five minutes to allow the examinee to access the test; extended inactivity or network connections can cause this. |
| 5027 | TestNav is unable to write to the local drive due to browser security settings. Testing cannot continue. | Contact your local system administrator; TestNav can't write necessary files to the local system. This is because the operating system is keeping the browser in a sort of quarantine (sandbox). Some operating systems do this to applications that can be used to cause system instability or other harm. Select a new location for student responses to be saved. If that does not work, view the student's responses and save or print a record of the files so that the responses can be reentered after you close TestNav and retake the test using a different machine. |
