Connection Not Private - Expired Certificate

[flowerdough]

I had a customer bring to my attention my website gave them a security message. They didn't feel confident checking out. When I visit my website, I see the same message.

"Connection Is Not Private - This Website Might Be Impersonating (www.flowerdoughclay.co) to steal your personal or financial information. You should go back to the previous page."

I haven't touched my website or changed anything in a month, at least. 

The details say my certificate has expired.

What do I need to do?
