Using webhooks in a N8N with VPN activated

Questions
1

Hey everyone. I have an N8N setup and use it in our internal databases. Now I need to use it with an external source (Meta for Developers) through a webhook and everytime we test the it I receive the following error:
“Callback verification failed with the following errors: curl_errno = 56; curl_error = CONNECT tunnel failed, response 502; HTTP Status Code = 502; HTTP Message = Failed to resolve host”

I think it might be related to the VPN, but I’m not sure how to solve it. Have you ever been through it? Any idea to share?

Thanks!
