[FSoD] Socket Error

I dont think i got this error before, but first time seeing it. This is what happens when i connect to my localhost server with my client.

my server ip and client both have same ip.



my client gets this error:



dont know why its happening. both Client.cs (server-sided) and the client has the same version.

maybe its something to do with something using your ip on a different sort of base like a forums or another server
