Are you hosting the website?
yes i created the website and it worked for me and stuff but now it won't and for other people it works.
This is more than likely due to something called NAT Loopback. A feature normally not available/disabled on routers you'll get from your ISP.
NAT loopback allows a machine on your local network to see the computer with your external IP address (domain in your case, which I assume is pointing at your external IP).
Without this feature you will be unable to see your site using your domain name. Depending on what you're using to run the server, you should be able to view it using localhost or 127.0.0.1
Hope this helps! Networking is sure frustrating lol.
