[MHFU] Socket Error(113)

Hello.

So recently i started to play MHFU with my friend and wanted to grind from scratch together , ive set up all the things required to start multiplayer LAN (from stickied thread)

the first time i did it it works fine and i can play quests at the online GH with my friend

until we are going to play again i cant seem to join online GH anymore ,it says Socket Error (113) couldnt connect to 192.xxx.xxx.xx/etc does anyone have encountered the same problem as i am? ( i've tried googling but its still the same)

here's what i did:
-We are playing on PC(host) - Android(client)
-We are using build-in AdHoc server
-i did everything as told at the stickied on how to set up LAN connection
(i've allowed inbound and outbound connection for ppssppwin64.exe)
-ive disabled fast memory on both device(if thats the case)
-Same Adhoc IP server Host-Client
-PROadhoc server checked on only the host
-Host(PC) started ppsspp first then client(android)
-both using same version of ppsspp 1.6.3
-both device near each other

host able to enter GH just fine but the client cant(few second loads and 'a communications error occured')

can anyone tell me what i did wrong? it was perfectly fine until the second time(few hours later) we tried to play ,
what does this socket error 113 means?
