It does say it is invalid but the problem is on my production server i am using JWT authentication & it is working fine. Since JWT has reached end of life, I have implemented OAuth. With it, I am able to:

1. Create webinar
2. Delete Webinar
3. Update webinar

But as soon as I try to Join the webinar, I get that error I mentioned.
