This is the same issue that @karolz-ms discusses here: https://github.com/dotnet/eShop/issues/42#issuecomment-1797016309. The proxy allows the connection, and then closes it. The client library (rightfully) logs this as an error because it doesn't expect the connection to be closed right after it is opened.
