SSL certificate expired?

HI

I added domains to Cloudflare for SSL but within Plesk I get the following message in regards to SSL
“SSL/TLS certificate used by this domain name has expired. Browsers consider such certificates a security risk and display a full-screen warning for all website visitors. To address this issue, get a new valid certificate from a Certificate Authority and install it”.

However, sites seem to be working fine and the URL shows https.

Hello,

Are you using either Flexible or Full SSL/TLS mode? If you are using one of those, Cloudflare doesn’t check your server’s certificate. You should change now that configuration and start using Full (Strict) SSL/TLS, and install an Origin Server certificate in your Plesk instance.

Hope it helps!
