what do we change on windows server 2k8 iis7 to fix "Secure Connection Failed" that is appearing with version 37 and 37.0.1?
We host https://www.prereg.net and the recent updates (version 37 and 37.0.1) have caused a "Secure Connection Failed" message to appear. We have contacted our hosting company and our SSL provider (geotrust) and neither of them are able to help with this issue. Can anyone tell us what we might need to alter on our server in order to fix this issue? We have a valid certificate and we have SSL3 and TLS 1.2 enabled.
Thank you very much for your help

I'd suggest following the setup advised here: https://wiki.mozilla.org/Security/Server_Side_TLS#Modern_compatibility
Your website accepts old cyphers, which are weak, https://www.ssllabs.com/ssltest/analyze.html?d=prereg.net
Godaddy should be able to help you update to a more secure system.
The browser console shows:
This site uses the cipher RC4 for encryption, which is deprecated and insecure.
