Hi Team…
I want to ask about my experience
Since February 2022, we have issue about error code 522:Connection Timed Out.
And I have more than 100 domain, and all of them support by Cloudflare.
So what’s wrong ?
And from July 2021, we use free licensed on Cloudflare, but what happened at February 2022? Because we always get error code 522.
Thanks
Greetings,
Thank you for asking.
I am sorry to hear you started experiencing an error 522 recently.
Regarding Cloudflare 522 error, may I suggest you to try looking into below articles to troubleshoot the issue:
May I ask to what does this refer to? 
Does the error happen only on one website or?
How frequently do you see it and in which circumstances?
Dear fritex,
I mean Free Plan on Cloudflare 
Not only one website, it becomes 50domain from 266 website
and this is analytic error code
last 24 hour still have 522 error code, and this has an impact on our domains coming down.
Our tentative solution, change from Proxied (Orange Cloud) to be DNS Only (Grey Cloud)
It means change the status of some important website domains only.
