Can't connect to certain servers.

[MattyMagnificent]

So i'm trying to connect to 158.69.222.110:10556
The server is up and working because my friends can connect to it.
I tried connect to a different server a while ago and it did the same thing.
When I tried to connect to their server on Minecraft or Teamspeak I would never get a response.

Whenever I try to connect this is what happens.

Trying to connect to server on 158.69.222.110:10556
Failed to connect to server

Here are the logs.

[.Fake.]

Well there are some issues with your plugins but
I can not see any error why you're not able to connect.

Is your client up to date?
Are you sure, those servers (Minecraft/TeamSpeak) are running?

It is also NOT IMPOSSIBLE that they have a whitelist.
TeamSpeak server supports white and blacklists, too.
But you're not on the blacklist which got confirmed with (13:46:04 ClientUI Info Blacklist check ok).

So there is client sided problem, maybe a problem with your firewall or router
or these servers are still have a whitelist system.
