This is definetly related to your internet and you can try the following:
-Connect to fgunz.net through a different device that is connected to your network and see if it works there. If it does; then either your antivirus or something else might be blocking your connection to the website on your device which you cant access the website with. If it does reply below.
-You might be IP banned (even though im not sure thats the message you would get if you were IP banned) so you might wanna see if connecting your device to a different network temporarily will load the website.
What error were you getting on your launcher?
