Intermittent 521 outage issue - investigate by Cloudflare Ray?

Hi there,

New user to Cloudflare. I have been seeing intermittent 521 errors from my users, with one of them providing the Ray ID: 572ac0950f0b65c7.

How can I dig deeper into what happened here?

You could open a ticket, but check this first:

My issue is intermittent - mostly random customers mentioning it. I can’t correlate it with errors on my web server.

How do I raise a ticket to try and get more insight?
