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.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
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
    NET::ERR_CERT_COMMON_NAME_INVALID

    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
