Certificate valid date problem

Follow up this thread, CloudFlare did sent to me another Certificate Transparency Notification with content like this:

Log date: 2021-11-19 00:23:33 UTC
Issuer: CN=Cloudflare Inc ECC CA-3,O=Cloudflare, Inc.,C=US
Validity: 2021-11-19 00:00:00 UTC - 2022-02-16 23:59:59 UTC
DNS Names: *.vnkeyfc.com, vnkeyfc.com

This time, seem the SSL certificate clearly from CloudFlare, not by SiteGround anymore, but when I chek directly on my website, it still show my valid date is 2021-12-14.

Is it really okay with my website, since it show the different SSL valid date from CloudFlare? Thank you.

Yes. The certificates need to be renewed before they expire, so Cloudflare generate a new certificate, and then replace the certificate before the old one expires. There always needs to be some overlap, otherwise the would not have time to deal with issues at the CA, or other issues with deploying the new certificate on their infrastructure.

So what should I do now?
The certificate CloudFlare sent to me via Certificate Transparency Notification have a different valid date with the current one show in my website (vnkeyfc.com), as I said above. I am verry worrying that there is problem with my website’s SSL.
