Looks like a bunch of different tests timed out all over the place, not just socks:

SocksProxyTest_Http1_Async.TestLoopbackAsync(scheme: "socks4", useSsl: True, useAuth: True, host: "localhost")

SocksProxyTest_Http2.TestLoopbackAsync(scheme: "socks4", useSsl: False, useAuth: True, host: "localhost")

SocketsHttpHandler_HttpClientHandler_MaxResponseHeadersLength_Test.SetAfterUse_Throws

SocketsHttpHandler_HttpClientHandler_Asynchrony_Test.ExecutionContext_Suppressed_Success

SocketsHttpHandlerTest_HttpClientHandlerTest_Headers_Http11.GetAsync_MissingExpires_ReturnNull

SyncHttpHandlerTest_Cookies.GetAsync_SetCookieContainer_CookieSent(cookieName: "ABC", cookieValue: "123", useCookies: True)

SocketsHttpHandler_RequestContentLengthMismatchTest_Http11.ContentLength_DoesNotMatchRequestContentLength_Throws(contentLength: 0, bytesSent: 1)

Http3ResponseStreamZeroByteReadTest_Mock.ZeroByteRead_BlocksUntilDataIsAvailable(async: True)

SocketsHttpHandler_HttpClientHandler_ConnectionPooling_Test.Http2_SmallConnectionTimeout_SubsequentRequestUsesDifferentConnection(timeoutPropertyName: "PooledConnectionLifetime")

Http1ContentLengthResponseStreamZeroByteReadTest.ZeroByteRead_IssuesZeroByteReadOnUnderlyingStream(readMode: AsyncArray, useSsl: False)

@rzikm can you please check frequency of failures?

[rzikm]

Looks like one-time environmental failure (no other hits between today and 1st March), closing.

More similar timeouts hit by #67147:

System.Net.Http.Functional.Tests.Http1RawResponseStreamZeroByteReadTest.ZeroByteRead_IssuesZeroByteReadOnUnderlyingStream(readMode: SyncSpan, useSsl: True) [FAIL]
      System.TimeoutException : The operation has timed out.
