Challenge failed for domain Error

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:

I ran this command: sudo certbot certonly --standalone

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Plugins selected: Authenticator standalone, Installer None

Enter email address (used for urgent renewal and security notices) (Enter ‘c’ to

cancel):

Starting new HTTPS connection (1): acme-v02.api.letsencrypt.org

An unexpected error occurred:

ConnectionError: (‘Connection aborted.’, error(101, ‘Network is unreachable’))

Please see the logfiles in /var/log/letsencrypt for more details.

My web server is (include version): standalone

The operating system my web server runs on is (include version): RHEL 7

My hosting provider, if applicable, is: AWS route53

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):
no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 1.3.0

I am a complete novice when it comes to creating certs and technical stuff so please bear with me

@LayiAdes,

Welcome to the community forum!

Are you able to make successful network connections outside of this server?

dig google.com
ping google.com
ping 8.8.8.8
curl -v telnet://github.com 22

So I have just set up on a different system and I am getting the following error:

[root@ip- letsencrypt]# sudo /usr/local/bin/certbot-auto certonly --standalone
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator standalone, Installer None
Please enter in your domain name(s) (comma and/or space separated) (Enter ‘c’
to cancel): blah.com

IMPORTANT NOTES:

We won’t be able to help you troubleshoot this if we don’t have the domain name.

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.
