Due to a recently discovered vulnerability in an outdated but still used internet encryption, SSL 3.0, a la mode has disabled the ability to connect to our servers through a connection secured with SSL 3.0. If your browser still has SSL 3.0 enabled, that may temporarily prevent you from logging in to your XSite, CertMail, or any other website hosted by a la mode. If you're unable to log in to any a la mode website, and instead get an error message, you will need to disable SSL 3.0 on your computer.
To help you disable SSL 3.0 on your computer, Microsoft has created a "Microsoft Fix It!" program that performs all of the work for you. To access Microsoft's tool, click here.
After running the Disable SSL 3.0 in Internet Explorer tool, simply log in to the a la mode website you were attempting to log into earlier.
