How can I troubleshoot a Safe Exam Browser error 403 when accessing an exam?

Troubleshooting a 403 error in SEB involves several steps: 1) Verify the exam URL in the SEB configuration. 2) Check the server logs for more detailed error information. 3) Ensure the server isn't blocking the IP address of the user. 4) Confirm the correct authentication details (if required) are configured in SEB or being passed by the LMS. 5) Test with a regular web browser to see if the issue persists outside of SEB.
