Can't generate ssl certificate, "Some challenges have failed."

There are some inherent complexities to using the same name for multiple systems.

  1. SNI fails to distinguish serverA from serverX
    when they are ServerA:portX and ServerA:portZ
  2. All HTTP authentication requests for EXAMPLE.COM will go to only one system/server/IP.
    ServerA:port80

It would really be more... useful if each server had its' own name.

mindset82.ccgeo.info = 45.202.17.189
mindset83.ccgeo.info = 45.202.17.189
mindset84.ccgeo.info = 45.202.17.189
