I have a few HTTPS certificates for a few domain names. I checked and they are set to renew with crontab. Today I found out that some of my websites are not working, I checked and some of the certificates expired in February 28 and were not renewed. I didn’t receive any email or notification about renewing the certificates but the websites just stopped working. For example for the domain speedysoft.com and some other domain names.
The command I run for renewing these certificates are:
sudo certbot certonly --dns-digitalocean --dns-digitalocean-credentials /home/uri/.certbot/digitalocean.ini --domains <list of my domain names> ...
Also, why do I have to renew the certificates every 3 months? I prefer to renew them every one or two years.
