It took me 5years to create a mulitplayer game in ue4 now time to package it i get this error Packaging failed: Error Unknown Error, someone help me, because i am about to retire from my hobby with ue4 forever, because its tedious.
Ok i figured out the problem myself.“packaged complete”
1-I removed the Advanced Sessions node and replace it with the Create Session Node,
2-then i moved up to UE4.16 and packaged and it work.
