Advanced Sessions Plugin

Im replacing OSS Null with Advanced Steam. Replaced all Find Session with Find Sessions Advanced and Create Sessions with the Create Advanced Session.

Using Steam works fine, can create a server and join to it with two different steam accounts. When I create a LAN server it seems to work and I can list it on clients. But when I press Join and go into Join Session, seems to reach it and print a string saying Success but never really joins the LAN Session and Open the Level. I created a new Event NetworkError and after 60 seconds I get a Time Out message.

What could be happening?

Thank you.
