It's been years I've using LE, but I got alert yesterday that the cert for my domain name is outdated.
That's when I realized the renewal is not working since april til today.
I tried to request a new cert, but got error message said "The domain name is invalid, make sure the domain name can resolve to public IP."
But I can still use both domain name and IP to access my website.
Please help since I have no clue why this happened.
My domain is: naviart.idv.tw
I ran this command:
It produced this output:
My web server is (include version): Synology NAS with Nginx
The operating system my web server runs on is (include version): DSM 7.1-42661 Update 3
My hosting provider, if applicable, is: Synology NAS
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): Synology DSM
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): N/A
