Hey @medikademia,

Thank you for reaching out to the Zoom Developer Forum. First, please make sure that you are generating the timestamp of the signature using a UTC timezone. You can find more information in our guide on Generating a Signature.

If that doesn’t help, can you share how you’re generating the signature?
