Messenger API DOES NOT VEREFID

I have a problem, which is that I created my own n8n service and connected it to ngrok and turned on the vpn so that it would accept my ip, then after that the n8n worked, but the problem is that the respond to webhook receives data well and shows the check mark, but the Messenger API does not authenticate even though the n8n receives data well. I also tried to turn it on my n8n service and the same problem?

Hi there can you share your workflow? so we can understand it better
