Hi,
I'm currently testing nginx 1.13.6 x64 on my development machine, which is Windows 10 1703 x64, and sometimes I got a "Secure connection failed" error on Firefox (55.x and 56). If I hit the reload button (F5) repeatedly, the page will eventually load.
Dev tools shows: 200 OK, size 0, and transferred -. nginx debug log doesn't show anything weird.
Things that I observed:
1. 1.13.5 works fine
2. Chrome on Android works fine
I've tested 5a3ab1b5804b, 46ddff109e72, and 924b6ef942bf and they have the same problem.
Configuration is pretty much default with HTTPS and HTTP/2 server blocks.
Thanks,
Joseph Aditya P. G.
