Can't Renew Certs

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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: data.algopti.com

I ran this command: certbot renew

It produced this output:
root@node-server-express-service:/etc/letsencrypt/live/myDomain.com# certbot renew

Hi @AlgoSignals

what says

ping acme-v02.api.letsencrypt.org

traceroute acme-v02.api.letsencrypt.org

PS: Checked your domain - https://check-your-website.server-daten.de/?q=data.algopti.com

Host T IP-Address is auth. ∑ Queries ∑ Timeout
data.algopti.com A 167.99.227.6 North Bergen/New Jersey/United States (US) - DigitalOcean, LLC No Hostname found yes 1 0
AAAA yes
www.data.algopti.com A 37.60.251.211 Chicago/Illinois/United States (US) - SiteGround Hostname: ip-37-60-251-211.siteground.com yes 1 0
AAAA yes

Your non-www is hosted via DigitalOcean, your www version via SiteGround.

And your port 80 + non-www is blocked, no connection is possible. So creating a certificate via http-validation can't work.

Hello, thank you; so what is the correct procedure?
I already had these certs on the domain and they expired today.
Someone else set them up so I’m not sure of the procedure they followed.
