Apologies as I’ve missed out the reply. Thank you for your respond.
Q: How many clients are you running? Does this occur when running one or two clients as well or only with more than that?
only when 2 or more…
Q: Which OSS are you working with?
4.15.1 Binary version
Q: Do you see any settings in your DefaultEngine.ini related to timeout, such as AsyncTimeout or P2PConnectionTimeout that you could potentially increase?
I have this under OnlineSystemSteam but I doubt it’s applicable in Editor
P2PConnectionTimeout=90, I will try increasing them. I also have “InitialConnectTimeout=120.0” under [/Script/OnlineSubsystemUtils.IpNetDriver] , what settings do you propose I increase and how much?
