— CDN Claude Feller
All webmasters or SEO managers of websites are familiar with Cloudflare. Installing a CDN will increase the speed of the site. But you should know that setting up a CDN can work for external hosts. But it is not a suitable option for Iranian hosts. If you’ve done this by mistake and you’re getting a 502 error, we suggest you disable Cloudflare’s CDN as soon as possible.
But sometimes cloudflare is active on external servers and works properly. But the 502 error is still observed. This error is temporary and resolves itself in most cases.
