That's the web server error. It's the origin server returns this error to CF. More information is here: https://developers.cloudflare.com/support/troubleshooting/cloudflare-errors/troubleshooting-cloudflare-5xx-errors/#error-520-web-server-returns-an-unknown-error
what if the error started showing at new deployments only? I have several deployments working perfectly fine, but once i retry these deployments, the website starts raising such errors
Have you checked the resolution tips from the attached doc? Check if it points to specific point. If the error were to take place at the new deployment, certainly, there would be logs too which would pinpoint the issue.
Logs were pointing to a db connection, but i fixed it by downgrading compatibility date
