Your destination IP address may not be active. If your custom A record points to a destination that is not yet active, you will see a "page cannot be displayed" error in your browser.
When creating a custom A record, please be sure that your host name is pointing to an active IP address. To confirm that the IP address is correct and active, enter the address directly into the address bar of your browser and click "Enter" or "Return," then verify that it resolves to the expected destination.
Your A record may also still be propagating. Custom records may take from up to 72 hours to be recognized across the Internet. We recommend that you test your A record again after this propagation period.
