Error 522 after deployement

My sites were showing, but after actualization, deploying to all sites, error 522 is displayed. Why is this happening?

Hi,

Error 522 usually occurs when Cloudflare times out contacting the origin web server.
Kindly reach out your hosting provider to check on this issue
