I'm trying to renew my SSL certificate in my AWS EC2 server but I'm getting the following error so after a lot of research I couldn't find the solution.
I ran this command:
$ sudo certbot renew --dry-run
It produced this output:

Hi @zainkhan , and welcome to the LE community forum
You have not provided enough information for anyone to help you with.
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.
