What is Certbot?
Certbot is an open-source software to obtain free HTTPS/SSL certificates from Let’s Encrypt.

Why Is Nginx Certified?
Nginx is an open-source web server developed by Igor Sysoev. Nginx is designed to be a higher-performance server than Apache, and is well-suited for powering high-traffic websites. Thanks to its modular design, Nginx can also serve as an SSL proxy, reverse proxy, mail proxy, database proxy, and load balancer.
Nginx is popular due to its low memory usage and high performance. In order to take advantage of all the benefits of using Nginx, it is important to configure it correctly with up-to-date SSL certificates. Certificates ensure that the server is properly authenticated and that the data is encrypted securely.
Why Is Certbot Necessary?
For many websites, setting up HTTPS/SSL certificates can be a daunting task. Let’s Encrypt is a certificate authority that offers free digital certificates to website owners and administrators. Certbot automates the process of obtaining and renewing digital certificates from Let’s Encrypt.
Certbot provides a simple command-line tool that makes it easy to obtain and install certificates. Certbot also provides an automated renewal process that ensures that the certificate is kept up-to-date. Certbot is an important tool for website owners and administrators to ensure the security of their systems and users.
What Does “Nginx Cannot Find Name” Mean?
When using Certbot to configure Nginx with Let’s Encrypt certificates, you may get an error message saying “nginx cannot find name”. This error occurs when the Certbot tool is unable to determine the domain name of the website. This could be due to a misconfiguration in the Nginx configuration files or an outdated certificate.
How to Resolve “Nginx Cannot Find Name” Error?
When you receive the “nginx cannot find name” error, you should first check the Nginx configuration file. Make sure that the domain name is correctly configured and matches the certificate. If the domain name is correct, you should also check that the certificate is up-to-date.
You can use the Certbot tool to renew the certificate. With the Certbot command-line tool, you can easily renew the certificate with the following command:
sudo certbot renew
If the renewal process fails, you can also try to manually obtain a new certificate with the following command:
sudo certbot --nginx --domain example.com
Conclusion
The error “nginx cannot find name” can occur when the domain name doesn’t match the certificate or the certificate is outdated. You can use the Certbot command-line tool to renew the certificate. With Certbot, it is easy to manage Let’s Encrypt certificates and keep your website secure.
