Elusive 12999 error code
Hey guys,

I've been receiving reports from several Android Chrome users that they're not able to visit our site, and I'm glad I found this tool. WebPageTest is showing a 12999 error code which is proving quite elusive.

Initially I thought this was due to our RapidSSL certificate, but a SSL Labs test [0] scores an A rating and I'm seeing the same result on both HTTP and HTTPS.

Please see the test results for both protocols [1][2] with 3 runs to avoid outliers, and would appreciate any pointers. I have not been able to replicate this locally with Chrome Dev Tools and as far as I can tell our DNS is setup properly.

Any suggestions?
