I received a mail from cPanel that the AutoSSL expiry on a specific date. Since I have configured cloudflare, should I be worried about the expiry date and take any corrective action?
If you have SSL set to Full (strict) Yes.
You should renew the certificate on your origin.
It is only set to Full, not strict. What else could be the issue?
CPanel does it’s job. Renew your origin certificate either with your hosting provider if you bought it from them or in CPanel if it is self signed.
I don’t know CPanel so I can’t tell you how to get a new cert issued there
