hi, my question is:
How can I extend the expiration date? and how can I automatically update a new date every 90 days? could you please tell me step by step? thanks.
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
You "extend the expiration date" by renewing the cert, which should be done every 60 days or so, and should be done automatically. If it isn't (and it hasn't since January of this year for that hostname--before that it was issuing new certs every three days in a gross abuse of the Let's Encrypt service), perhaps whatever resources cPanel has can tell you why that product isn't working properly.
Yes, it's called "renewing" and as I said, how to do that is related to how you got the certificate in the first place. Instead of using the command line or hit a button to "get a certificate" you'd use a command line or button to "renew the certificate". But as you haven't told us how you got the certificate in the first place, we cannot give you any advice on how to renew
AutoSSL would have renewed the certificate automatically. Please check your AutoSSL configuration in cPanel. More info can be found at https://blog.cpanel.com/autossl/
