Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Hi @carvalhomayk Welcome to the Community.
Your error explains the issue.
PORT STATE SERVICE
22/tcp filtered ssh
80/tcp filtered http
443/tcp open https
Port 80 needs to be open for the process to work.
Firewall? Router? ISP?
Check it out.
ALSO:
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. crt.sh | example.com), 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:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
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):
More information would be extremely helpful for the volunteers here.
It produced this output:

Does your ISP block port 80?
Are you using a firewall on your webserver? If so which firewall are you using?
Oracle Linux Server is packaged with firewalld... are you using that?
If so please post the output from:
sudo firewall-cmd --zone=work --list-all
If not...
Do you have a separate firewall between your webserver and your router?
Port 80 has to be OPEN to the world. Something is blocking access to it.

ASA by default inspects the traffic leaving and allows the returning traffic to pass through without any need for any ACL, but if you want to allow the traffic initiated from outside to inside, you need an ACL entry to allow it.
Please inspect your ACL via cli or the GUI and adjust it to allow port 80 to the target server accordingly.
EDIT: The Cisco Community is the best place for information on how to do that if you are not familiar with the process.
