If you are trying to access a World but are experiencing an error, it may be due to being on a VPN.
A VPN is a virtual private network that organization oftentimes use for network security. If you are using a VPN, you may need to have the World's URL whitelisted with that VPN. Please contact your organization's administrator to request the World's URL is whitelisted.
In the meantime, or if the World's URL is whitelisted, refresh your DNS cache by referencing one of the flush options below:
Windows DNS flush
Search for Command Prompt using Windows' normal search feature. Click the Start button and type in Command Prompt, and then select it from the list when it appears.
Right-click Command Prompt and select Run as administrator or click it in the results, you'll open an elevated Command Prompt.
Once open, type in the following command and press Enter.
"ipconfig /flushdns"
Flushing DNS will clear any IP addresses or other DNS records from your cache. This can help resolve security, internet connectivity, and other issues. It's important to understand that your DNS cache will clear itself out from time to time without your intervention.
That should update your local DNS cache, and you should be able to get to your World.

If you are using the Chrome browser, you can also clear your host cache.
Open a new Window and enter into the browser:
chrome://net-internals/#dns
After hitting Enter you should see option to Clear host cache.
