steam multiplayer not finding sessions

I am having problems trying to find sessions(getting none) in both my game, and the multiplayer shootout. I have the steam overlay, right now using the testid,I have tried in the same pc and in different pcs too.
How can I trouble shoot this problem everything seems to be to hidden inside sessions, I beg for your help.

more info: there is something about steam failing gracefully too that is failing, when I launch the project from the editor I can create sessions even if steam is not running, when I build and launch the project it won´t be able to create sessions if steam is not running.

for anyone else trying to do this, the system works it is just that if you use the test dev id 480 the sessions you will get will not be useful for your game, you are getting sessions from hundreds of other people using that id. Epic could try to sort this out but it will take a long time I think.
