My domain is: blockchain.korea.ac.kr
I ran this command: certbot certonly --csr /etc/letsencrypt/csr/0002_csr-certbot.pem --apache
It produced this output: TLS-SNI-01 is deprecated, and will stop working soon.
My web server is (include version): Apache 2
The operating system my web server runs on is (include version): Ubuntu 18.04
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): certbot 0.28
I have been proceeding with certificate renewal via the command “certbot certonly --csr”.
I did not use “renew - dry - run” because I had to keep my private key, public key.
However, there has recently been an issue(“TLS-SNI-01 is deprecated, and will stop working soon.”.)
I found that I had to use renew --dry - run in step 3 of “How to stop using TLS-SNI-01 with Certbot” to find the solution.
I would like to know if there is a way to solve this issue using “csr” as usual.
