Oh, boy. An online service that analyzes secure connections sees numerous problems with that site, including:

  • The SSL certificate expired in February 2016
  • None of these browsers work with the limited set of ciphers offered by the server:
    • Firefox 47-49
    • Chrome 49 and 51
    • IE 11 or Microsoft Edge
    • Safari 10

They must know about this problem, right?!

Normally this error occurs on a website that is outdated in still supporting RC4.

RC4 support has been completely removed in Firefox 50 as it is no longer able to be overridden. https://www.fxsitecompat.com/en-CA/docs/2016/rc4-support-has-been-completely-removed/
