Single/Multiplayer, Touch & Vive blueprint only Template

Hello, I’ve got connection problems between host and client over simple Lan. The client sees the host match and I can join, but upon clicking “Launch” the menu disappears and the Host level isn’t loaded (this should happen right???). Have a Vive -PC and an Oculus-PC as participants. No matter which is host and client, the client don’t load the map. Using your " Template 3_2_2_Packaged" (after I thought it’s my faulty application based onto ) and have the problem. Please help me, multi user VR is badly needed for my project.
