What is Cloudflare Error 520?
Cloudflare is a well-known content delivery network (CDN) and security service that stands between your website and the people who visit it. problem 520 is a status number that shows up when a server that is a gateway or proxy for a website has an unexpected problem.

What causes Cloudflare Error 520 to happen?
Cloudflare Error 520 can be caused by a number of things, and to fix it correctly, you need to find out what they are. Some of the common reasons why people make this mistake:

- Error 520 means that Cloudflare requests can’t get through because your server’s firewall isn’t set up correctly. It is very important to make sure that your security rules are set up correctly so that Cloudflare’s IP addresses can get through.
- If you have a Web Application Firewall (WAF), Cloudflare and your main server might have trouble talking to each other. Error 520 can happen if the rules are too strict or if the settings are wrong.

How to Fix Error 520 in Cloudflare?
Now that we’ve talked about the most common causes of Cloudflare Error 520, let’s talk about what you can do to fix it and get your website back up and running:
