Anytime I open Minecraft and try to join my friend's world it says the term "getsockopt" which tells me it's a connection error and I have tried many methods such as Restarting My Computer, Deleting and Reinstalling Minecraft, and allowing it through my fire wall which all have no difference. The connection error is only on that one specified server and all my other servers work fine.  The connections also don't work for direct connection and the server is not a Lan server rather a server hosted by my friend. The server is the only one having the problem and the problem is on my side because everyone else can play on it just not me.
