After enabling Letsencrypt certificate, not able to access my website from browser(This site can’t be reached)

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., 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 yum install snapd
sudo systemctl enable --now snapd.socket
sudo snap install core; sudo snap refresh core;
sudo ln -s /var/lib/snapd/snap /snap
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
sudo certbot --apache

It produced this output: Congratulations! You have successfully enabled

My web server is (include version): apache (wordpress platform) and domain is from Godaddy

The operating system my web server runs on is (include version): Oracle Linux 7.8

My hosting provider, if applicable, is: Oracle Cloud

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 1.10.1

Kindly support immediately, my website is down for more than 10 hours.


You need to open port 443 to allow HTTPS to work.


443 port is opened but still getting same error. see the below traces:

[opc@uwayinstance1-380831 conf]$ curl -v telnet://uwayinstance1-380831:443

  • About to connect() to uwayinstance1-380831 port 443 (#0)
  • Trying
  • Connected to uwayinstance1-380831 ( port 443 (#0)

That shows port 443 is listening. And can be connected to locally (IP
It doesn't show that the Internet can reach it via port 443.
Is there a firewall?

I get:

curl -Iki
curl: (7) Failed to connect to port 443: Connection timed out
curl -Iki
curl: (7) Failed to connect to port 443: No route to host

Yes there was firewall . thanks a lot for pointer.

I run below command and then it works fine:
sudo firewall-cmd –-permanent –-zone=public –-add-port=443/tcp


I'm glad you were able to solve your own problem.

Cheers from Miami :beers:
