Overview

The Let ’s Encrypt certificate has been updated to add a subdomain to Let ’s Encrypt.
Subdomain addition has been confirmed with the sudo certbot certificates command.

After checking with the browser, the old certificate is still loaded. No subdomain has been added to the SAN item, and the authentication deadline has not changed.

1) Delete the certificate once and get it again
2) Restart Application loading pem file
3) Try accessing from a different browser, IP, or device

I tried all the above, but the old certificate remains.

Question

If i re-acquire a certificate, isn't it loaded on Sug?
