Event notification endpoint URL not getting validated

I am trying to validate this URL "https://devcommunity.minimeal.com/api/zoom-webhook", but it gives an error like “URL validation failed. Try again later.”.

Earlier, I used an ngrok URL for my local system, which worked fine.

hi @Wolfgang

Have you checked against the documentation?
~Are you using the new secret token method?

yes, I am using this method, which is mentioned in the documentation

if (event === "endpoint.url_validation") {
      const hashForValidate = crypto
        .createHmac("sha256", zoomSecret)
        .update(payload.payload.plainToken)
        .digest("hex");
      return res.status(200).json({
        plainToken: payload.payload.plainToken,
        encryptedToken: hashForValidate
      });
    }
