Google Domains SSL Certificate Not Applied to Subdomain on EC2
You have added a subdomain record to your Google Domain, linked it to the IP address of your EC2 instance, and yet, 24 hours later, it still says "not secured". This article will provide a detailed context of the topic, cover key concepts, applications, and significance of SSL certificates, and troubleshoot why the SSL certificate may not be applied to your subdomain on EC2.
What is an SSL Certificate?
SSL (Secure Sockets Layer) is a standard security protocol for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites to protect their online transactions with their customers.
An SSL certificate is a digital certificate that authenticates the identity of a website and enables an encrypted connection. SSL certificates are issued by Certificate Authorities (CAs), the most well-known being GlobalSign, DigiCert, and GeoTrust.
Why Do You Need an SSL Certificate?
An SSL certificate provides three key benefits:
- Data encryption: Protects sensitive data, such as credit card information, transmitted over the internet.
- Data integrity: Verifies that the data sent between the server and the browser hasn't been tampered with.
- Authentication: Confirms that the website is who it claims to be, preventing man-in-the-middle attacks.
In addition, Google has announced that websites using HTTPS will receive a ranking boost in their search algorithm, providing an SEO benefit to websites that use SSL certificates.
Google Domains and SSL Certificates
Google Domains provides free SSL certificates for your domains and subdomains through Let's Encrypt, a non-profit Certificate Authority. Let's Encrypt provides free, automated, and open SSL certificates, allowing you to enable HTTPS on your website with ease.
When you add a subdomain to your Google Domain and link it to an IP address, Google Domains will automatically issue an SSL certificate for the subdomain. However, there can be instances where the SSL certificate is not applied correctly, causing the "not secured" message to appear.
Troubleshooting SSL Certificate Issues on EC2
If your SSL certificate is not applied to your subdomain on EC2, there are a few things you can check:
- Check that the subdomain is correctly linked to the IP address of your EC2 instance.
- Check that the SSL certificate has been issued for the subdomain by visiting
https://your-subdomain.your-domain.comin your browser. - Check that the SSL certificate has been correctly installed on your EC2 instance. This can be done by checking the SSL certificate information in your web server's configuration.
- Check that there are no firewall rules blocking port 443, the default port for HTTPS traffic.
- Check that your web server is configured to use the SSL certificate. This can be done by checking the web server's configuration files.
SSL certificates are an essential part of website security, providing data encryption, data integrity, and authentication. Google Domains provides free SSL certificates for your domains and subdomains through Let's Encrypt. However, there can be instances where the SSL certificate is not applied correctly, causing the "not secured" message to appear.
By following the troubleshooting steps outlined in this article, you can ensure that your SSL certificate is correctly applied to your subdomain on EC2, providing a secure connection for your website's visitors.
