Try joining through skywars.com and doing /classic or /economy or /skyblock to get to your desired server.
I feel like he's trying to join the server either on Win10 edition or through a cracked account/cracked version of Minecraft. This won't work - Windows 10 has a different network protocol and different Minecraft system altogether, and cracked Minecraft won't work because, of course, no authentication is given to the server. You'll need to buy Minecraft Java Edition before you can join the server Unless it's a different error, in this case I'd be incorrect. What error message is being shown when you try to connect?
