Secure connection failed in version 37.0.1 but works in all other browsers and firefox 36
Very similar issue to this, https://support.mozilla.org/en-US/questions/1056423. Am able to get to http://www.independentagent.com and then when the 'sign in' link is clicked (which redirects to https://sso.iiaba.net/login.aspx?sid=xxx) this error shows:
Secure Connection Failed
The connection to the server was reset while the page was loading.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.
I ran the sso.iiaba.net domain through https://www.ssllabs.com/ssltest/analyze.html?d=sso.iiaba.net and it reports a few warnings but gives the site an overall rating of B.
- Fixed. As noted we were supporting old ciphers. We trimmed and resorted the cipher list and now we get an A on the ssllabs.com scan. Firefox works now, no problems. I wish the original error message was more descriptive.

The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases or may be using a deprecated cipher suite.
You can open the about:config page via the location/address bar and use its search bar to locate this pref:
- security.tls.insecure_fallback_hosts
You can double-click the line to modify the pref and add the domain (sso.iiaba.net) to this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). You should only see domains separated by a comma in the value column.

This site uses the cipher RC4 for encryption, which is deprecated and insecure. login.aspxRead this answer in context 👍 12
This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1.[Learn More]
