I see cloudflare 522 error and I found this troubleshooting guide
How I Solved My Cloudflare Error 522:
After hours of testing and trouble shooting (maybe months for CM?). I came upon a forum thread that claimed to solve the issue by deleting the domain on Cloudflare, reinstall Cpanel, then finally add that domain back to Cloudflare to fix the problem. I figured that was a lengthy way with long downtime for this kind of error. It seemed that deleting the account on Cloudflare and reinstalling it solved the problem, so maybe it is actually one of the Cloudflare settings.
If You are a website visitor and see error 522 then your best bet is to let the site owner know that this error message has occurred. The chances are that there is nothing for you to do on your end.
However, it has been reported by some that flushing your DNS may solve the issue. If the failed connection occurred due to website migrations for the ones that you want to access. But nevertheless this is an odd situation that does not occur often. So the odds are the the issues are still with the Cloudflare or Website.
Due to the nature of the error, there is a high chance that the site owner nor the hosting companies cannot replicate the error on their end. But if you experience it frequently, it is best for you to contact the website owner directly about it.
https://wordpresscheat.com/fixing-cloudflare-error-522/ipconfig /flushdns (in a command prompt to flush DNS) but I've done that and it only seems to bypass the cloudflare 522 message... as you can see the website is still fk'd
And No. my research won't be posted on this forum. That would only give the scammers time to clean up. Send me a DM if anyone are interested. My interest in this is limited but I can do my part if anyone wants to share notes.
