Hello, I’m currently experiencing an issue with webhooks. Square seems to have difficulty reaching my Ngrok URLs when I’m in production, I always receive 504 error, but everything works fine in sandbox. In sandbox, with the same URL I am receiving status code 200.My ngrok supports “https” and I am sending a response as 200 for any incoming webhook. I am using the globally available Nodejs SDK.

Have you tried separating sandbox from production rather then having both configured to help debug?
At any point of time, either my sandbox is connected or my production. Both of them are not active at the same time.
My sandbox webhooks are working perfectly fine but my production webhooks return only 504 error code.
