Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

There have been issues reported caused by using some SSL cipher suites that aren't working properly with some servers.

You can do a test for issues caused by one or more cipher suites and disable all SSL cipher suites on the about:config page (i.e. toggle security.ssl3.* prefs that are true to false) and enable one at the time to see if you can find a culprit and keep this suite disabled and reset the other cipher suites or possibly continue testing to see which ciphers work with this server.

Do a hard refresh of the tab with this not working page via "Ctrl+F5" or "Ctrl+Shift+R" after each change.

how do i post this publicly accessible page. can you provide the link

Which website is causing this SSL issue?

If you could post a link then we can check this certificate to see if we can reproduce this error.

https://meet.up.edu

It works if I disable TLS 1.2 by setting the security.tls.version.max to 2 (or 1).

• http://kb.mozillazine.org/security.tls.version.*

0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, 3 means TLS 1.2 etc.
