I presume you have tried the LPE Connectfix installer?

I'm not sure about the reported error as I cannot see the entire log.
How about instead installing WireShare which is the continuation of LPE but with several bugs fixed. WireShare should in theory be a little easier to connect with. https://sourceforge.net/projects/wireshare/

Make sure you make a firewall exception for WireShare. If necessary also forward a port. Port forwarding is far more reliable than UPnP which tends to stop working during long sessions. Also some routers do not have UPnP support.
