[Tutorial] How to play multiplayer on one PC. testing PPSSPP adhoclocal

[Radarow]

I have "socket error (10065) when connecting to 127.XXX.XXX.XXX/127.XXX.XXX.XXX:27312". Of course I have enabled buil-in pro serve and run this one first. You can trust me that I do everything correct like in tutorial. I think its something wrong with my internet. I found this information on microsoft website:
WSAEHOSTUNREACH
10065
No route to host.

A socket operation was attempted to an unreachable host. See WSAENETUNREACH.

I don't know what this mean and what I should do, because I not too good in things about internet.
