When using the steam subsystem and packaging my game, my other test computer can run it on its own steam account, but when its run on my steam account the online sessions fail to create every time. The only solution I have found is to use a different steam account but that is a work around at best. I have also contacted steam support just in case but if this is a problem that anyone knows the solution I would love some help.
