Your webhook endpoint is not responsive-Issue

Dear Zoom team,

We have received an email with regard to the validation of our webhook. We have attached a screenshot of the validated webhook, However we have still received an email which suggests that it has not been validated.

Kindly help us sort this situation, as we have validated the webhook. Do let us know if we have to take any further steps to avoid any service disruption.

I am attaching below the copy of the email that we received this week.

Your webhook endpoint is not responsive, please review this email for details.
