This is my first time building a server and hosting it to AWS EC2. When running the command sudo certbot certonly --standalone or sudo certbot certonly --webroot I recieved this error below
Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems: Domain: matthieuxroger.com Type: unauthorized Detail: Invalid response from [18.205.22.32]: "<!DOCTYPE html>\n<html>\n <head>\n <title>Matthieux Roger</title>\n <link rel='stylesheet' href='/stylesheets/style.css' />\n "I am using nodejs on ubuntu 20 running on AWS EC2. Any help would be apprieciated.

When using the webroot method with Certbot, a web server is spun up that serves a single file, so that Let's Encrypt can verify the ownership of the server at a domain. But when LE accessed your domain, it got a different server that served a 404 page. It seems that the DNS for your domain isn't pointing to the EC2 instance that is requesting a certificate. (or perhaps it has been updated but just hasn't propagated yet). You need to update the DNS records to point to the server requesting a certificate with certbot. Alternatively, you can use a different challenge type that doesn't require running a server to prove ownership (such as dns-01).
check the domain name server in your domain name registration that you have just the A record point to your address and delete other A records
