Ports won't open. However they are setup correctly. Is it possible that IIS was setup wrong? I ran into this issue before myself and just started over and it seemed to work.If it works on the VPS then it's a config, ports problem or the links are wrong to connect outside of the VPS.
This might be the case.If it's a Cloud server try this tutorialYou must be registered for see links
Yeah it will be this tutorial if it's a cloud server, I setup something on a cloud server and couldn't get it to work a while ago, had no idea why. Wish I had this tutorial thenThis might be the case.
I found this on the VPS providers website @Vaping
Firewall management
The external firewall automatically protects you from attacks. Individual firewall rules can be set centrally in the cloud panel.
