I recently updated to UE4.24 and having massive issues with the Steam Integration and Dedicated Servers. The project and dedicated servers where running perfectly fine in older engine versions (unfortunatly I have spent so much work in the last 2 weeks within UE4.24 that reverting back to an old Engine version is not possible).
If I launch the game as a client (standalone) the steam integration works perfectly fine. When I build the Dedicated Server the below Log is printed where it states that ***Steam Dedicated Server API failed to initialize. ***The Server is not listed and cannot be found, if I launch with the -NOSTEAM command it obviously failes to create a session.
So here is the question - What changed from UE 4.22 to 4.24 to massivly destroy the Steam Integration for dedicated servers?
I have tried many different DefaultEngine setups (all you can find on google and in the documentation) as well as for the Server Target file. There seams currently no way to launch a Dedicated Server with the currently given informations.
How can I fix this?

DefaultEngine (I changed the AppID to SpaceWar just for this example):
I run on 4.24.1 and, while I can’t see the dedicated server under the Internet tab on Steam, it does successfully initialise and it is shown under Lan tab.

So the only difference I see is the order and missing value on Achievement_0_Id(not sure if no value is considered as empty string).
Everything works fine using the space war app id: 480
But using my own app id the server starts ok, but client can´t see in steam servers tab or find session.
I’ve had the exact problem when upgrading to 4.24 but was able to resolve the OSS shutting down by making sure my steamclient.so file was up to date (might be steamclient.dll for windows). The steamclient.so file updates usually each SDK upgrade and if you have an older versions the OSS cannot start.
Not sure why you’re having these issues, but I’m having No issues in 4.24 with dedicated servers. Using these settings: SteamCore & Dedicated Server - eelDev
I did managed to fix it. I was running the older steamworks sdk and the new engine does not include this by default. I copied across the ‘Steamv142’ to the EpicGames\UE_4.24\Engine\Binaries\ThirdParty\Steamworks folder and it fixed it.
I have the same problem with Steam Achievements, but I have already the ‘Steamv142’ into the Steamworks folder. Did you need to do anything else other than that?
