I recently went through the mess of following outdated tutorials and various sources to get Steam multiplayer working for Unreal Engine 5, and after figuring out all of the gotchas (and some <a href="https://forums.unrealengine.com/t/ue-5-5-online-subsystem-join-session-always-results-in-on-failure/2125579/5" target="_blank" rel="noopener nofollow">engine bugs breaking the advanced sessions plugin</a>) I wanted to summarise my findings in a YouTube video to share with all:
Video: <a href="https://youtu.be/5nMKEKV0acI" target="_blank" rel="noopener nofollow">UE 5.5 Steam Multiplayer Setup &amp; Testing in 10 minutes</a>
I also made a &lt;1 min <a href="https://youtube.com/shorts/ffcPShidWmA" target="_blank" rel="noopener nofollow">Shorts version</a> that summarises all of the steps very quickly, but is really more of a taster for those who care to check out the full video.
Hope it helps anyone else looking to do this, and I’d love to hear any feedback here or on YouTube re production quality or future tutorial requests as I feel there’s still a big gap in the UE tutorial space for 5-minute concise, clear, and up-to-date information.
