Than Steam is on, can’t find session. Than it’s off session success found.
Min slots available = 0
Set it higher
don’t worry we have all been there.
I think if it was a foult , it won’t work without steam, but if steam off, it’s working
of course because if its off the slots available are = 0
Also there is a bug I have run into with bp sessions that will show a session available even if you never started one. It happens like every other game i make. I dunno why but it has been reported.
happens with or without advanced sessions.
just thought I would add that.
Oh Crud … i forgot how to fix that. I know you have to change something in your ini file but I forget what… let me look at ue4 forums and see if I can find it again.
Look here
Are you using Lan ? or steam
If using lan then you need to check that on your sessions
If your using steam then this question is out of my league sorry 
Ok, it’s don’t work(
I don’t use steam, but it’s start’s from one pc using one steam accout. One from engine one from client. Can it be error?
I would review.
and make sure you have everything correct.
The way i understand it is that if your using the steam subsystem you have to connect through steam.
you cant connect a lan game with steam and a lan client cannot connect to a steam hosted game without using steam.
Again my skills with steam subsystem are limited but i am pretty sure of this.
For everyone using steam having the same problems: The steam servers are region locked. I don’t know if it is only for AppID 480 but still worth a try.
If you and your friend are not in the same region it will not connect. You can change your region by changing your download region in
SteamClient>>Steam>>Settings>>Downloads>>DownloadRegion. Make sure your friend and you are using the same servers.
Thanks so much, this helped me so much!!!
I have set the same region for both of my steam accounts (I’m testing from 2 separate computers, on 2 separate steam accounts)
Most of the time it isn’t able to find a session even when I’ve hosted one, it only sometimes randomly works after relaunching the game on both of my devices, but that too has a low success rate
I would really appreciate if you provide some insight regarding this 
Hey, let’s say it’s pretty hard to debug externally if it works “sometimes”, without seeing anything of your setup.
Make sure you update your Steam SDK to the latest version.
Also make sure you start both games using the same version, with compiled binaries (if you use C++).
Sometimes it wouldn’t connect, if i forgot to compile after changing some code.
Can you post more of your setup? Then i can take a look at it. Else i can just give you general advice.
