Issuing wget cannot fetch certbot-auto

[nutzer]

I ran this command:
wget https://dl.eff.org/certbot-auto

It produced this output:
Resolving dl.eff.org (dl.eff.org)… 151.101.108.201, 2a04:4e42:1a::201
Connecting to dl.eff.org (dl.eff.org)|151.101.108.201|:443… failed: Connection timed out.

My web server is (include version):
c6g.12xlarge

The operating system my web server runs on is (include version):
Amazon Linux 2

My hosting provider, if applicable, is:
AWS

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

How can I get cerbot-auto downloaded?

Does your networking work at all?

curl -I -m10 https://google.com
curl -I -m10 https://fastly.com

There seems to be no problem with the network connectivity and the Inbound Rules for the EC2 instance allow access from anywhere for both http and https.

Issuing curl -I -m10 https://google.com returns the following:

Something else I noticed is Amazon Linux 2 requires a different command to enable EPEL. However, upon issuing the command to enable it, which is recommended by AWS, I encounter the following error:

sudo yum install http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Failed to set locale, defaulting to C

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd

Cannot open: http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm. Skipping.

Error: Nothing to do

Researching more into this issue has revealed that the problem lies in the VPC of AWS and has probably nothing to do with Certbot.
