I just ran into this error again on Mac. You can find the test run here.

System.Net.Http.HttpRequestException : An error occurred while sending the request.
---- System.Net.Http.CurlException : SSL connect error

I would expect System.Net.Test.Common.RemoteServerException : Likely external issue with remote server in the exception. Was that not the case?

[rmkerr]

No. The exception and stack trace look very similar to what is mentioned in the issue description, but I don't see any reference to System.Net.Test.Common.RemoteServerException : Likely external issue with remote server
