Unable to prove HTTPS (possibly due to cypher suite issues)

Hi,

The keybase daemon currently reports my HTTPS prove to be broken. I am however able to obtain and verify it by following the link for the HTTP prove (http://burnus.net/keybase.txt), or using https:// respectively, and piping the result into `keybase verify`. My guess is that the issue has to do with the fact that my server only accepts a few carefully selected HTTPS cypher suites (TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030), TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) and TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014)), which are not yet supported by all the SSL libraries. Can you please elaborate on which cypher suites you support on your end?

Thanks.

Start by reproducing the HTTPS prove failure for https://burnus.net/keybase.txt and compare it with the working HTTP prove and `keybase verify` flow. Investigate compatibility with the three listed TLS cipher suites; done means the supported suites and the cause of the failed HTTPS prove are documented or the prove succeeds.
