I am currently working on a project which should allow users on the LAN to host sessions from an Android device and join them from the HoloLens 2. I have tried creating the same project in Unreal Engine 4.2.7 and 5.0.3.
Issues
I can create sessions from the Android device and they can be found from the PC and other Android devices on the same network, however the HoloLens 2 does not seem to find any sessions on the LAN. I am attaching the blueprint screenshot where I create the session.
In the image below you can see that I am able to find sessions from the PC but when I run the application on the HoloLens 2, it does not find any sessions on the LAN.
@jas.singh99 Have you tried to create a session from the Hololens and join the session from the PC? I have done it and it works, but I would need the other way round!
I found out why I wasn’t able to find sessions on LAN from the HoloLens. There is nothing wrong with the HL2Collab example - and the BP from @jas.singh99 , my work account (because of some security policies set by my employer) was blocking the network traffic. That explains why if I created a session on the HoloLens, I was able to join from my PC.
Switch to a local account and it does work like a charm!
Hope this helps.
UPDATE: my answer does not solve your issue though. I can’t find sessions too, but I can connect to the listening server on my PC from the Hololens. I have used the following BP to join the session:
