LAN Play with (PC) PPSSPP and PSP

[melancholicman]

Hi, I've tried to play patapon 3 (psp+ppsspp) but can't connect on psp. My psp sees the connection(the "hideout" in game) but when i press it, it immediately says that can't connect with other "hideouts".
upnp - turned on
renamed pspnet_miniupnc.prx
disabled iso cache in recovery
enabled memory in recovery
two empty lines are in hotspot and server files

I guess connection is ok if psp sees it so router must be ok

What can I do?
