Mup deploy using CLoudflare return 500 error

I Have auto ssl setting in MUP : proxy: {ssl: { letsEncryptEmail: 'mywebsite@mail.com'} }

Everything about https was working fine, Both before and after it uses Cloudflare .

Except that it throws 500 errors at times everyday After i enabled the Cloudflare. (I can’t make sure if it’s the same Before swichted to Clouflare, but i never seen)

I have a screenshot showing some of the Hardware usages and I Think it’s not a problem about my server image|545x500

I also tried removed the proxy setting from mup. then my website throw 500 error only, And won’t getting better no matter how many times refreshing or changing the browser.

Is there anyone using Cloudflare for Mup? If you are please share some configurations or solutions

I found an error in the proxy logs:

;1mnginx.1    | ;1m2020/08/22 02:25:07 [alert] 2306#2306: 1024 worker_connections are not enough
[173.82.238.68]2020-08-22T02:25:07.902778140Z ;1mnginx.1    | ;1m2020/08/22 02:25:07 [alert] 2306#2306: 1024 worker_connections are not enough

How do i solve it for Mup
