Janar told me to go to Command Propmt and fill in 'ping 95.141.37.186'. It shows me this: Packets sent: 4, packets received: 0, packets lost: 4, [100 percent packetloss]
Nope. Try adding "95.141.37.186:7777" to your favorites.
You can also try going to command prompt, type in tracert then Argonath's IP (95.141.37.186) so it'll look like tracert 95.141.37.186. however it's not reliable. Sometimes, it could be a firewall problem on your end as it was with mine. This is a routeban.

Try doing a jitter test
here.
Also, does it say "Server is restarting", "Lost connection to the server" or "Server closed the connection"?
