I have been using Cloudflare for years without issues but today I am getting Error 522 on multiple files across 22 sub domains on my server. My web host say the CF IP Ranges are whitelisted so this is not the issue.
I get the generic “Error 522 Connection Timed Out” page
Also if I connect with a VPN the sites load as normal, normally when this has happened in the past it fixed itself and started working after say 10 minutes. It’s now been over 48 hours since the sites were loading as expected.
All of the sites were working fine a few days ago but today nothing is loading and nothing has changed to my knowledge.
Does anyone know what could have triggered this?
