Certificates are not getting generated

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. crt.sh | harhu.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: harhu.com

I ran this command:
sudo certbot certonly --agree-tos --email hello@harhu.com --webroot -w /var/lib/letsencrypt/ -d harhu.com -d www.harhu.com

It produced this output:
Failed authorization procedure. www.harhu.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://www.harhu.com/.well-known/acme-challenge/AcqCgIXzn9YWw6gZDrUnZBA_6K6O7kUjHdZedhYpyxI: Timeout during connect (likely firewall problem), harhu.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://harhu.com/.well-known/acme-challenge/DsVxhRy3SjL2wohwleg_ud9Re3I94DjqbierzNA8MHY: Timeout during connect (likely firewall problem)

Hi,

Do you happen to have a firewall or something in place where it blocks access to your port 80? I also couldn't access your website on port 80. You need to fix your ports before attempt again.

Hi @Harhu

there is your error. Please fix that. A working port 80 is required.

AWS has something like a security group.

Thanks, let me try to active port 80

Now your port 80 answers, that's good :+1:
