I have a multiplayer project where clients tries to server with “Find Session” Blueprint node. It works fine when testing locally in the same Windows machine with packaged EXE, but once I try to run it on a corporate WiFi, where I work, the node neither fails nor succeeds - it just executes through the default pin.
Any ideas what might be going on? Some evil corporate security tricks? 
Hey there @PatMag68! The default port for UE multiplayer is 7777, is it possible this is blocked outgoing on your system? How much user access does the exe have when it launches?
The EXE has full user access. And I forgot to mention that it works fine if the server IP is input manually (with port 7777). It’s the Find session node that fails.
Interesting! Does it fail with both the Use LAN bool on and off? Does this work on a closed LAN network away from your work’s? I’m inclined to believe it’s environmental, but we’ll have to see.
Yes, it fails with both LAN on and off. It executes through the default pin of the “Find Sessions” node, so it neither succeeds nor fails.
If I instead enter the IP manually of the server PC, it works just perfect. Weird.
