It gives me this error Problem running workflow Bad request - please check your parameters Details : 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

So want to set up the n8n whasapp trigger which runs when message is recieved but it always gives this error

  • You appear to have some problem with your SSL setup. (A bit of research on the error message suggests that "wrong version number" is not always accurate; the same message can appear when the response is not a TLS response at all.) Suggest you put your endpoint URL through a couple of the available SSL checker tools online, and see what those have to say first of all. Commented Sep 26, 2025 at 13:32
