When attempting to reach my exposed REST service I am getting a 403 Forbidden response. On my rest service I have Requires Authentication set to No and it is working without authentication on my localhost Studio Pro. In the live log I get – [error] 243#0: *3 access forbidden by rule, I know that my URL is correct. Seems to be an issue only in production.
Check the firewall settings. You probably need to expose the endpoint. Check the documentation.
