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: cubacatering.avianet.cu
I ran this command:sudo certbot --apache
It produced this output:Saving debug log to /var/log/letsencrypt/letsencrypt.log
Enter email address (used for urgent renewal and security notices)
(Enter 'c' to cancel): ******@gmail.com
An unexpected error occurred:
ValueError: Requesting acme-v02.api.letsencrypt.org/directory: Network is unreachable
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): Apache 7.4.3
The operating system my web server runs on is (include version): Ubuntu 20.04
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 1.24.0
I followed the instructions of this topic Running certbot behind proxy? but it didn't work. I run certbot behing a http proxy
Is the HTTPS_PROXY environment variable set in the shell where you are running Certbot?
echo $HTTPS_PROXY
You may also need to run Certbot with sudo -E, if the environment variable is not available from the root user's shell.
The advice from the other thread is suitable to make sure the scheduled task runs with the environment variable set. But it won't help when running Certbot from a terminal.
Sorry, i'm quite new at this, I ran this in my terminal, no outputs. Then I tried again the steps of the other thread with sudo -E certbot --apache, same error
An unexpected error occurred:
requests.exceptions.ConnectTimeout: HTTPSConnectionPool(host='acme-v02.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f3f8457e520>, 'Connection to 192.168.x.x timed out. (connect timeout=45)'))
That was the output, please, remember that I'm behind a HTTP proxy, shall I use this command?: export HTTP_PROXY=http://192.168.x.x:port
To my understanding, the meaning of HTTPS_PROXY is "the proxy server to use for HTTPS requests". You can still pass an HTTP (insecure) proxy to it.
Most likely, you will need to set both HTTP_PROXY and HTTPS_PROXY, because Certbot uses a mix of secure and insecure requests. The latter is due to OCSP queries.
Well, that's some forward progress.
If you omitted the port number when you set HTTPS_PROXY, try including it.
Otherwise I would double check that the proxy URL is correct.
