Anyone? I’m stuck with this.

3

When you create a session is the level you are opening with extra parameters like “listen” ?

4

Thanks for helping me :slight_smile:
Yes I did put listen.
I made server browser and session is there client can see it and it shows server name.

Edit:
I am using steam.

Edit 2:
May be it doesn t work because I am doing all the logic in my menu widget.

6

I haven’t dealt with steam yet, but have you got the SDk needed fr steam?

7

I had an issue like this today.

Turns out even though I defined the OnlineSubsystem to NULL, because I had steam open, it used that. Try closing steam, if you have it open.

8

I just set up my DefaultEngine.ini
All dll files are there by default I think.

9

I will try that :slight_smile:

10

I tried closing steam but it didn’t help.

11

I will send the game to my friend and we will try to connect.

12

Hey man, did you get this to work? I am having the same problem with Joining a LAN session with Steam on

13

Same here i am having the same problem. I tried 3 differents projects and still get this message in the logs : LogOnline:Warning: NULL: Can’t start an online session (Game) in state InProgress
I am using Steam in France.

14

Hello. Do you have a spaces or NOT-english symbols in Computer-name? If you have, rename it.

15

I’m from eastern Europe and also have a problem with Joining Session. Currently I’ve tested 4.19 - 4.20.1 without success. Previously without big problems on 4.17 version. I’v tried any free and paid steam samples without success to join session. LAN and dedicated server working fine. In 4.17 I needed to press button about 7 time to successfully join the session. I’ve tried any passable things to crack steam join session. Renaming user and computer names, tried 3 different internet providers, about 10 different steam sample codes and projects from internet. Changed PC, steam accounts, used unreal source build with updated steam SDK to 1.42. Used all available advanced session scripts. Nothing was helpful in my case. I’m getting following errors in my logs:
