The connection to authserver.mojang.com can no longer be established because none of the server's cipher suites are supported by the launcher.
This is most likely because it relies on the operating system to support these.
On the ssllabs report you can see that IE11 on Windows 7 and 8.1 can not connect.
Relevant lines from the launcher log:
