Why does my PageSpeed Insights report show "Failed to load resource: the server responded with a status of 404 (Not Found)" for image URLs using blogger_img_proxy, even though the images were previously loading fine?

This is a tricky one! It sounds like you're using blogger_img_proxy to serve your images, which can sometimes cause issues with PageSpeed Insights. Here's a breakdown of why this might be happening and how to fix it:

Possible Causes:

• Caching Issues: PageSpeed Insights might be hitting a cached version of your page where the images weren't loading correctly. Try clearing your website's cache and running the test again.
• Temporary Server Errors: Sometimes, the blogger_img_proxy server might experience temporary outages or glitches, resulting in 404 errors. This is usually resolved quickly, so try running the test later.
• Incorrect Image URLs: Double-check that the image URLs you're using with blogger_img_proxy are absolutely correct. Any typos or incorrect formatting can lead to 404 errors.
• Firewall or Security Issues: A firewall or security plugin on your site might be blocking requests to blogger_img_proxy. Temporarily disable these to see if that resolves the issue.

How to Fix and Prevent 404 Errors:

1. Verify Image URLs: Meticulously check every image URL in your PageSpeed Insights report. Make sure they are accurate and accessible.
2. Test Image URLs Directly: Open the image URLs in your browser to confirm they load correctly.
3. Clear Cache: Clear your website's cache (and your browser's cache) and re-run the PageSpeed Insights test.
4. Check blogger_img_proxy Status: If you suspect a problem with the proxy itself, try using a different image proxy service temporarily to see if the issue persists.
5. Review Firewall/Security Settings: If you have a firewall or security plugin, temporarily disable it and re-run the test. If the images load, adjust your firewall settings to allow requests to blogger_img_proxy.
6. Consider Alternative Image Optimization: For long-term reliability, consider using a more robust image optimization solution like a CDN (Content Delivery Network) with image optimization features. This can improve loading times and reduce the reliance on external proxies.

Remember:

• User Experience: Always prioritize the user experience. Make sure your images are optimized for fast loading and display correctly on all devices.
• PageSpeed Insights Score: While a good PageSpeed Insights score is important, it's not the only factor in website performance. Focus on providing a smooth and enjoyable browsing experience for your users.
