Good day.
I cannot say that I have seen your specific error when using OKTA.
One thing that comes to mind is checking to ensure SSO is properly enabled.
- Sign in to the Zoom web portal.
- In the navigation menu, click Advanced then Single Sign-On.
- Click Edit in the top-right corner.
- In the Service Provider (SP) Entity ID section, check or uncheck Automatically manage the certificate.
Are you using the pre-built application from OKTA or did you build a custom app within OKTA? Did you follow the public support article for OKTA specifically?
https://support.zoom.us/hc/en-us/articles/115005719946-Configuring-Zoom-with-Okta
Can you share screenshots of the authentication settings as well as how you are using authentication from the Zoom Apps?
If the above SSO and/or OKTA support link have resolved your problem, please mark the question as solved so that others may quickly and easily find help with similar problems. If this has not resolved your problem, please feel free to reach out again.
