Wine version? Terminal output? Steps to reproduce?
Great questions, I'm sorry for not giving more details. This was meant as a placeholder, until I figured out those details.
On wine versions < 5.7, I was able to reproduce this very consistently. Now I feel silly, because I cannot reproduce this at all on 5.17 in the case of Legends of Runeterra.
When I was testing this on wine < 5.7, the terminal output did not contain anything related to this; however I may have missed the right debug channel. However, when I did try to track that down (by following an unobfuscated version of GameAssembly.dll), I came to the conclusion that the websocket disconnect was initiated by the client because of a "timeout". I am certain that the timeout was unreasonable, because I wrote a reverse proxy that printed the websocket packets in real time, and the supposed timeout was shortly after receiving packets.
As for reproduction steps, on wine versions < 5.7 staging (or any version with my patches from #47970 applied to staging and before the ntdll PE split), getting into a Player VS Ai game in Legends of Runeterra ( https://playruneterra.com/en-us/ , free to play however a Riot account is needed ) surely ended with a disconnect at about the 3 minute mark from connecting to the game. (Reproduced the issue for me basically 100% of the time)
More testing will be needed to see if this was fixed at some point, as I cannot reproduce this on 5.17 at this time. (To test this with Runeterra on 5.17, the staging patch "ntdll-NtQueryVirtualMemory" needs to be rebased, which I will try to submit separately)

If it's using winhttp websockets, note that support was added in Wine 5.12.
