I am creating a third party integration from Site24X7 and added Production Webhook URL for n8n in Site24X7. When I send the test trigger, n8n app flow is not able to listen to the event and I get the error on Site24X7 which states that “Access to the configured URL is not allowed. Check your Firewall.” What am I doing wrong is it authentication or authorization issue as pings are going to webhook site successfully
