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:
I ran this command:
sudo certbot renew --standalone --dry-run --pre-hook "service nginx stop" --post-hook "service nginx start"
It produced this output:
Simulating renewal of an existing certificate for video-feeds.utccuip.com
Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Detail: 126.96.36.199: Fetching http://video-feeds.utccuip.com/.well-known/acme-challenge/v_RbkQenWkGfVhwIKd5m_oWrbpTjoxoImFyxPfcTqBk: Timeout after connect (your server may be slow or overloaded)
Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.
Failed to renew certificate video-feeds.utccuip.com with error: Some challenges have failed.
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
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):
I am using the standalone method - therefore I stop nginx as a pre-hook and start it post hook in order to free port 80 during the renewal process.
