Start by reproducing the Steam store or community failure and trace the reported paths through SteamworksLocalApiServiceImpl.Initialize, ReverseProxyHttpClientHandler.ConnectCallback, and HttpReverseProxyMiddleware.HandleErrorAsync. Compare the failed upstream requests with the 502 and disposed IServiceProvider errors. Done means the affected Steam pages and acceleration flow work without these errors, with regression coverage where the existing test structure permits.
