hi @hector.vazquez , how are you?
That is typically an issue with the configuration settings. I’d suggest the following, visit https://jwt.io/ and paste there your access token. The site will automatically decode your token and give you information about its payload on the right side of the screen.
Validate the audience and issuer values on your settings with the fields iss (issuer), and aud (audience). They have to be the exact same values, including the last forward slash if any /.
Let me know if you had any differences in your settings and if that fixed the issue.
Thanks,
Juan
