400 The Plain Http Request Was Sent To Https Port

Are you experiencing issues with your website's navigation and loading times? It may be due to a simple redirect from HTTPS (secure) URLs to HTTP (non-secure) URLs. In this article, we'll explore the causes of such redirects, their effects on internet performance, and best practices for troubleshooting and resolving these issues.

Based on our research, website redirects from HTTPS to HTTP can cause connection errors or 404 Not Found responses. This is often due to a misconfigured server or a lack of SSL/TLS encryption on the server-side. When a browser sends an HTTPS request, it expects a secure connection. If this isn't met, it will default to the non-secure protocol and may result in errors.

Furthermore, some website redirects can also lead to inconsistent loading times or slower page loads due to the additional HTTP requests being made by the browser. This is especially true for websites with complex content or multiple images.

What You Should Do

So, what can you do to resolve these issues? First, ensure that your server is configured to use SSL/TLS encryption. This will automatically redirect any HTTPS requests to HTTP and prevent connection errors.

Another solution is to enable CORS (Cross-Origin Resource Sharing) on the server-side if necessary. This will allow your website to handle non-secure requests from scripts running in other domains. You can find more information on CORS configuration in our previous article, "400 The Plain Http Request Was Sent To Https Port: A Step-by-Step Guide.

Best Practices

Here are some best practices to keep in mind when dealing with website redirects from HTTPS to HTTP:

By following these steps and best practices, you should be able to resolve the issue with website redirects from HTTPS to HTTP. Remember to stay vigilant and monitor your website's performance regularly to catch any potential issues before they become major problems.
