I need help with Error 522(host Error)

Hello, I need to ask how long will Error 522 take? I get it every next week and I don’t know what to do. Please tell me how to fix it or something.

Depends what have you already tried to fix it?

Can you post your domain name here so we could check?

Have you already changed your nameservers to Cloudflare ones at your domain registar?

Have you tried following the steps from as written in the article from below?:


Have you allowed Cloudflare IP addresses to connect to your new host/origin?
Maybe you need to allow Cloudflare IP addresses to connect to your host/origin server:


Have you got an SSL certificate for the needed hostnames of the domains?
Can you check what have you got selected under SSL tab at Cloudflare dashboard? Is it Full SSL or something other?

522 occurs when
Before a connection is established, the origin web server does not return a SYN+ACK to Cloudflare within 15 seconds of Cloudflare sending a SYN.
Or, After a connection is established, the origin web server doesn’t acknowledge (ACK) Cloudflare’s resource request within 90 seconds.
There maybe something hogging up your resources, causing the connection between cloudflare and the origin web server to time out and the connection to fail.

What’s the website URL? Maybe I’ll get the same error.
