Greeting, @andresavic,

Thank you for posting in the Zoom Developer Forum. If you’ve encountered a 401 error when you tried to join to your webinar, it’s most likely due to Invalid/missing credentials:

As a test, can you either clear your browser cache or try to join the webinar from a private window ? This will help to rule out a possible cache issue.

I am looking forward to hearing back from you.
