Steam Multiplayer

I make Steam Multiplayer with blueprint and INI configuration added. After packaging I start to Host and my fend click 9-10 times before enter in my game. When he host I click over 100 times when i try to connect, but I connect successful only one time. Why this multiplayer is not stable and what I can do?

How many games are you getting from FindSession function? Also, are you using development game id or you have already your own game id?

I found 1 game. I dont know for this id, i using Pyrodev tutorial
Unreal Engine 4 - Steam Multiplayer - YouTube

So, looks like you are using DevAppId (480), a lot of other devs are using it. So probably you are searching for their session and you are not able to connect to them.

There are few solutions for this case:

  1. Increase number of Max results in Find Session

  2. If you have steamworks, buy a place for new application - then you will get your unique app id.

  3. Highjack app id of one of the game from you steam library that you and your friend own and that doesn’t offer multiplayer support.
