@BrennanConroy, @anurse I believe there was some internal issue which has caused many issues to fail with this handshake failed issue a while ago. That issue was, if I'm not mistaken, root caused to some runtime issue, which was later resolved. I'm going to un-quarantine this test.

[BrennanConroy]

Don't know any details about that, but I'm assuming this hasn't failed for a while?

[mkArtakMSFT]

I haven't been able to find any of these tests in the Quarantined Tests view in WhatsBroken. Was thinking about unquarantining this.

[BrennanConroy]

These tests aren't running in Helix, so you can't use WhatsBroken to see if they are failing or not.

The issue is still there.
