Unsupported protocol

I'm a subscriber to several Daily Kos email newsletters, including Daily Kos Recommended and Sign If You Agree (petitions). Some days I can't access any of the links in the email. Every attempt gives me a security block with the message:

This site can’t provide a secure connection
u1584542.ct.sendgrid.net uses an unsupported protocol.
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.

What is the problem? Why does it happen? Can I do any thing about it from my side?
Thanks for any advice or assistance.

    Same thing here, started yesterday, Jan 11 on both, phone and computer.
    Message is a bit different:

    Your connection is not private
    Attackers might be trying to steal your information from u1584542.ct.sendgrid.net (for example, passwords, messages, or credit cards). Learn more

    How do we fix it?

    Am experiencing the same invalid certification message on both the computer and cell phone when I click on any link with Daily KOS in its name. However, I find I can get into the site by typing in a URL starting with http\\:www.dailykos.com. Have I picked up a hack somewhere?

    Same problem - Safari tells me to close page as it is not secure. Has the Daily Kos certificate expired?

    This may be a "work-around". But can anything be done about the problem
    itself? - Ron
