Cannot connect to CalDav on windows 8 - Win XP works fine.
-Same current version of eM Client on both machines 6.0.20154.0
-Same CalDav calendar and user configuration on both machines.
-CalDav is running on a secure server with signed cert
-can connect to the CalDav server using a webclient with no errors on the Windows 8 machine
-If I run Fiddler in HTTPS decrypt mode, the Windows 8 machine will connect and work as long as fiddler is working.
-Windows 8 machine gives this error:
