Hi Team, We are changing the infrastructure , the app was hosted in. Due to that I want to subscribe the new url "https://api.stream8.uat.heliosalliance.net/pace-fbwebhook/webhook" in the webhook subscription.But getting below error. "The URL couldn't be validated. Callback verification failed with the following errors: curl_errno = 28; curl_error = Connection timed out after 6000 milliseconds; HTTP Message = Unknown Response Code."

Could you please increase the timeout period for more than 6000 milliseconds. And Could you please share the detailed error message.

And we have disabled all the firewall policies.

We cannot subscribe the new webhook url in the App. Getting The URL couldn't be validated. Callback verification failed with the following errors: curl_errno = 28; curl_error = Connection timed out after 6000 milliseconds; HTTP Message = Unknown Response Code. How to resolve this.
