The site https://dlc.iec.cat/ stopped working in Firefox 57 Nightly. It shows a "Secure Connection failed" error message and I cannot add an exception. It works OK in Firefox 55 (release). The main site https://www.iec.cat is working fine in Firefox 57 Nightly,

Any clue?

I can confirm this in Nightly. The current Beta and Developer Edition versions (56) still work This server only supports TLS 1.0 and TLS_RSA_WITH_3DES_EDE_CBC_SHA for Firefox.

This site works for me if I enable this cipher suite on the about:config page (the only one that is false).

  • security.ssl3.rsa_des_ede3_sha

Note that there are also intermediate certificate issues.
