Single/Multiplayer, Touch & Vive blueprint only Template

Hey , thanks for the new update! Downloaded the template and compiled it to check if steam hosting was working, without any success. We tried to use it with a guy in the uk with an oculus running steam and me in Argentina with a vive hosting the server. Then we swap and either two ways couldnt see the server for joining. All the things mentioned on the pdf for steam success were doubled checked.
any ideas? Thanks in advance!
