Can not renew certificate

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: ns1,consumer,gov.ua

I ran this command: certbot -q renew

It produced this output:
Attempting to renew cert (ns1.consumer.gov.ua) from /etc/letsencrypt/renewal/ns1.consumer.gov.ua.conf produced an unexpected error: Failed authorization procedure. ns1.consumer.gov.ua (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://ns1.consumer.gov.ua/.well-known/acme-challenge/0iPTsD2D_4ahSac124eV7qIVwa7FbfRggBXxJQgei9g: Timeout during connect (likely firewall problem). Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/ns1.consumer.gov.ua/fullchain.pem (failure)

My web server is (include version):
coturn
The operating system my web server runs on is (include version):
Ubuntu 18.04.4 LTS
My hosting provider, if applicable, is:

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 0.31.0

I get the same problem:

curl -Iki ns1.consumer.gov.ua
curl: (7) Failed to connect to ns1.consumer.gov.ua port 80: Connection timed out

Lets Debug also shows a similar problem:
https://letsdebug.net/ns1.consumer.gov.ua/145198

In case you haven’t noticed, port 80 is required for HTTP authentication.
You should check that HTTP is running and accessible form the Internet.

And you may need to move quickly:
