I followed a simple HOST, SEARCH, JOIN LAN networking tutorial on youtube: - YouTube.
It seems like everything should work because it just uses the HOST, FIND, JOIN blueprint nodes. It works if I run the server and the client on the same computer; however when I try one computer being the server and another computer (on the same network) being the client, the client can find the session, but goes black when it tries to join.
Any help would be greatly appreciated!!!
