Error: 'Setup was Unsuccessful. Please try again. Error [23]' When Starting or Joining a Meeting

Error: 'Setup was Unsuccessful. Please try again. Error [23]' when starting or joining a meeting 

I receive an error 23 when starting or joining a meeting on the Firefox browser.

Error 23 when trying to start or join a meeting using Google Chrome.

Cause:

This issue may be caused by a known bug that was resolved in WBS33.7. If your site is on the Lockdown version, WBS33.6, you may encounter this error as the lockdown version did not receive the fix.

Workaround:

Try using the Web App (Start or Join Meeting by Browser method). For help, see: https://help.webex.com/9eed9t/Get-Started-Joining-a-Meeting-with-the-Webex-Web-App
