csworldlet.top

### Error Message

My website opens very slowly, so I use a CDN, and just now, when I was using the CDN to cache my “/wp-content” folder, my CDN reported an error: When the CDN node requested the origin server, the request was interrupted by the origin server’s firewall. What should I do?

You might need to use Cloudflare instead of the plugin you were using before, also because Cloudflare is a CDN.

Thanks for the reply, my NS is on CF and I don’t use CF as my CDN. it’s strange that my site shouldn’t be opening properly right now if I follow the rules you mentioned, so I’m confused.
