Error 404/ DNS lookup (website mysteriously doesnt exist?)

just today I realized I could not enter this website I usually go on. Its called doodletoo.com and I cant enter the website. Here is the message that I got,




The server at doodletoo.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
Check your Internet connection.
Check any cables and reboot any routers, modems, or other network devices you may be using.
Check your DNS settings.
Contact your network administrator if you're not sure what this means.
Try disabling network prediction.
Go to the Chrome menu > Settings > Show advanced settings... and deselect "Predict network actions to improve page load performance." If this does not resolve the issue, we recommend selecting this option again for improved performance.
Allow Chrome to access the network in your firewall or antivirus settings.
If it is already listed as a program allowed to access the network, try removing it from the list and adding it again.
If you use a proxy server...
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Chrome menu > Settings > Show advanced settings... > Change proxy settings... > LAN Settings and deselect "Use a proxy server for your LAN".
Error code: ERR_NAME_NOT_RESOLVED
