Outgoing reliable buffer overflow error

One of my friends is trying to play minigolf with me and they keep getting an error that reads “Outgoing reliable buffer overflow”. It shows in the minigolf chat that they join but then immediately leave. Is this a known issue and is there a fix for this?

I’d try setting an FPS limit if you’re the host. There’s a current issue with the Unreal engine that makes hosts with high FPS (more than 60+) cause connection troubles sometimes.
