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 web server is (include version):
The operating system my web server runs on is (include version):
Linux #1 SMP Thu Dec 15 20:31:06 MSK 2022
My hosting provider, if applicable, is:
OpenLiteSpeed (EC2 Instance launched on AWS)
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):
p.s. I went to https://check-host.net/ and tried all the tabs. They all responded with normal statuses. But when I went to try the "Ping" tab, all results came up as "Result 0/4 traceroute"
This error suggests that your server can't make the necessary outgoing connection to the Let's Encrypt API server. Can you think of a reason why that could be? Is there any firewall or configuration that you would expect to be blocking outgoing connections from your server?
Could it be the EC2 instance? Does the EC2 have the ability to block these operations coming from this server? If so then maybe it can be a port forwarding issue I don't know. I checked security groups and ports 22, 80 and 443 are all allowed.
So I'm guessing the area I need to be checking is the server of the VPS? I bought this from OpenLiteSpeed which is the VPS hoster which I used to launch an EC2 instance. Is this where I should fix the DNS resolving issues ?
I have found the reason for this, my AWS account services was limited by the AWS support team due to a recent compromise in security credentials. Kind of a bummer that they don't explicitly mentioned the services that were affected! It is working now.
