Let's Encrypt Renew Certificate Issues

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: www.thechemicalhut.org

I ran this command: sudo certbot renew --dry-run

It produced this output:

IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: www.thechemicalhut.org
    Type: connection
    Detail: Fetching
    http://www.thechemicalhut.org/.well-known/acme-challenge/dGWtG0y6OgI8dRjapdyjGTEeZfHq8eB0ys6kfRf-pjw:
    Timeout during connect (likely firewall problem)

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

My web server is (include version): nginx/1.15.3

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: digitalocean

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):

It looks like you probably have a firewall installed on your Ubuntu setup.

Try:

ufw allow http

Also check in the DigitalOcean control panel that you haven’t accidentally enabled the firewall without permitting port 80.

Thanks.

Sorted it was the firewall from digitalocean that was the issue.
