Getting lots of errors such as this in the Gun test suite with a freshly built master, even for the most basic test. I think all tests are failing without exception. I'm using self signed certificates on the server.

Thank you for your prompt report.  Hopefully it should work again now, we found that we where lacking a test case for improper chains of only a self-singed peer cert.  The bug could also have affected chains with no intermediates. So please try again to make sure we did not miss anything else.
