Slack’s Porduction event listener isn’t working

My workflow is active, and configured production and test URLs successfully. But test one works, production one does not work. In production when I test workflow it triggers slack event listener. But when changing it to the Production URL it is configured but does not listen to the Slack event.

Screenshots

  1. slack configuration for production and test URL
  2. Workflow
  3. slack response in production mode (Not Working)
  4. slack response in Test mode (Working fine)

What is the error message (if any)?

No Error
