WhatsApp Trigger: (#2200) Callback verification failed with the following errors: curl_errno = 35; curl_error = OpenSSL/1.1.1zb: error:1408F10B:SSL routines:ssl3_get_record:wrong version number; HTTP Status Code = 200; HTTP Message = Connection established.

and then try to add the webhook url from the whatsapp node in the meta then it gives this error →

The callback URL or verify token couldn’t be validated. Please verify the provided information or try again later.

Hey @RamRider3366 ,

It sounds like you’re encountering an issue with the WhatsApp Trigger node in n8n. Here’s what might be causing the errors and how to fix them :-

SSL Error (curl_errno = 35)

Cause : SSL handshake issue between n8n and WhatsApp servers.
Solution : Ensure your environment supports the required SSL version. Update your SSL libraries if needed. If the issue persists, try running n8n on a different server or environment to see if it resolves the issue.

Callback URL Verification Error

Cause : Meta (Facebook) can’t verify the Webhook URL or verify token.
Solution : Double-check that the Webhook URL and Verify Token match exactly in both n8n and Meta settings. Ensure your URL is publicly accessible without any firewall or restrictions blocking it.

Are you using a self-signed certificate? That could be the problem, as I read about on the Meta page and setting up webhooks.

Nope

We are using proper certificates
