The test is failing here:
https://github.com/dotnet/corefx/blob/344c31c7ba9bc171bbab31167acdd279e9f6027c/src/System.Net.Http/tests/FunctionalTests/HttpClientHandlerTest.cs#L777

The request seems to have been canceled. This is all using the loopback server. It's likely that some delay is happening starting these async tasks and HttpClient cancelled the request after the default 100 seconds.

We haven't seen this failure lately. So, I'm closing this issue.
