Not Redirect To Https With Nginx Reverse Proxy And Certbot

Introduction

HTTPS is the secure version of the HTTP (Hypertext Transfer Protocol) that encrypts communication over the web. Having an HTTPS URL makes your website safer and is becoming a must-have for websites and web applications.

Https redirection refers to the process of sending a website user from an unencrypted URL (HTTP) to an encrypted URL (HTTPS). A common practice for webmasters is to use a reverse proxy and Certbot to automatically redirect visitors to an HTTPS site. However, this method can sometimes result in the website not properly redirecting to HTTPS.

Setting Up Nginx

Before setting up an HTTPS redirection, the webmaster should first configure the web server with Nginx. It is an open-source web server application designed to increase the performance and reliability of web applications. The general configuration options for Nginx can be found in the nginx.conf file located in the web root directory.

The Nginx configuration should include the necessary server blocks to properly proxy requests. Each server block should have a valid domain name that is associated with the web application. Additionally, the webmaster should configure Nginx to listen on port 80 or 443 for incoming requests. Nginx should also be configured to use the appropriate TLS/SSL settings to ensure secure communication.

Setting Up Certbot

Certbot is the most popular tool for obtaining and managing TLS/SSL certificates for websites. Certbot automates the process of obtaining certificates and ensuring they are updated and renewed on a regular basis. It is recommended to use the standalone option for Certbot. This will generate a self-signed certificate which can be used for HTTPS redirection.

Once the proper Nginx setup and Certbot configuration have been completed, the webmaster should create a virtual host file to begin the HTTPS redirection. This file should be located in the web root directory and should contain the following configuration parameters: SSL cert, SSL cipher, SSL protocol, and SSL prioritization.

Configuring the Nginx SSL Parameters

The SSL parameters configured in the virtual host file should be the same as those specified in the Nginx configuration file. This includes the SSL certificate and cipher. Additionally, the webmaster should ensure that the SSL protocol and prioritization are properly configured. To verify that the parameters are set correctly, the webmaster should use the testssl.sh script to make sure all of the SSL parameters are configured correctly.

Enabling HTTPS Redirection

After verifying the Nginx and Certbot configurations, the webmaster should enable the HTTPS redirection in the virtual host file. To do this, the webmaster must add the following lines of code: if ($scheme = “http”) { return 301 https://$host$request_uri; } This will enable Nginx to automatically redirect any requests on the HTTPs port to the correct HTTPS URL.

Testing the HTTPS Redirection

Once the HTTPS redirection has been enabled, the webmaster should test to make sure the website is properly redirecting to the HTTPS version. This can be done by loading the website in a browser and inspecting the URL. It should show that the website is using a secure connection and that the URL uses the HTTPS protocol.

Webmasters can also use tools such as Qualys SSL labs or the Browserforce test from Sucuri to further verify the HTTPS redirection and the overall security configuration of the website.

FAQs

What is Certbot?

Certbot is the most popular tool for obtaining and managing TLS/SSL certificates for websites. Certbot automates the process of obtaining certificates and ensuring they are updated and renewed on a regular basis.

Can I test the HTTPS redirection?

Yes, you can test the HTTPS redirection by loading the website in a browser and inspecting the URL. Additionally, you can use tools such as Qualys SSL labs or the Browserforce test from Sucuri to further verify the HTTPS redirection and the overall security configuration of the website.

Conclusion

Https redirection is an important part of having a secure website. Using a reverse proxy and Certbot can make this process easier and more automated. However, sometimes the website may not properly redirect to HTTPS. In this case, the webmaster should ensure that the Nginx and Certbot setup is properly configured, and that the correct parameters are set in the virtual host file. This should ensure that the website is properly redirecting to the HTTPS version.
