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 | 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: milohome.tplinkdns.com
I ran this command:
certbot certonly --nginx --dry-run -d milohome.tplinkdns.com -n --agree-tos
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Simulating a certificate request for milohome.tplinkdns.com
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Detail: Fetching http://milohome.tplinkdns.com/.well-known/acme-challenge/8U6z-WRGPPVMA-xkTfa4i-ofpw3FHrET1uSwPINQqAI: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
My web server is (include version):
nginx version: nginx/1.14.1
The operating system my web server runs on is (include version):
CentOS Linux release 8.5.2111
My hosting provider, if applicable, is:
None. Note that this is a domain owned by my ISP. It was given along with my home internet subscription. I don't own this domain.
I can login to a root shell on my machine (yes or no, or I don't know):
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):
Tried searching different topics on the same issues but it didn't help. Verified that my provider is not blocking port 80 and 443. My web server host firewall is not running. There's more debug log in the attached log. Based on that log, if I'm not mistaken, my connection to letsencrypt server is fine.
Where should my
.well-known/acme-challenge/ absolute path be?
