Servers Can't resolve hostname?

[GenPartyTV]

I know exactly how to connect to the website, but every time I try, It says "Can't resolve hostname". I have tried multiple servers, but it makes no difference and I keep getting the same message :/

What IP did you put in?
The "can't resolve hostname" error is usually when the IP was put in incorrectly
