Slow Website Loading & 521 Error Code

Locked

Tags: Google, Operating Systems, Windows

I’m currently facing a serious issue with my website; it takes over a minute to load. This prolonged loading time frustrates visitors and likely impacts engagement. Sometimes, the loading time increases to 4 minutes, and after that, a “521 error code” occurs.

I need urgent assistance in identifying and fixing the root cause of this slow performance. I would greatly appreciate your guidance if anyone has expertise in website optimization or troubleshooting slow-loading sites.

What steps can I take to improve loading speed and enhance overall performance? Are there specific tools or techniques you’d recommend for diagnosing and resolving this issue effectively?

https://www.google.com/search?q=html+error+521 makes me think it’s something with Cloudfare. Do you use that service?

To determine that that’s the cause indeed, make a test-homepage that doesn’t use it.

A slow website and 521 error code can be frustrating, especially when it impacts user experience and security. The 521 error usually means that the web server is down or not responding to Cloudflare requests. Here are a few possible causes and solutions:

1. Server Issues
The origin server may be offline or misconfigured.
Check if your hosting provider is experiencing downtime.
2. Firewall Blocking Cloudflare
Some security settings or firewalls may be blocking Cloudflare requests, leading to a 521 error.
Whitelist Cloudflare’s IP addresses in your server’s firewall.
3. SSL/TLS Misconfiguration
If your SSL settings don’t match Cloudflare’s configuration, it could cause errors.
Ensure your SSL certificate is correctly set up and compatible with Cloudflare.
4. Slow Website Performance
If your site is loading slowly along with the error, consider:

Optimizing images and compressing files.
Enabling caching for faster load times.
Using a Content Delivery Network (CDN) like Cloudflare to distribute traffic efficiently.
