this error started after i updated node js
Was your web application working over HTTPS prior moving to the Cloudflare?
Yes, I was already using Cloudflare and it was working normally, after updating the version in node js, I get this error 520, I have the site paused in Cloudflare to have access now
May I ask what steps for troubleshooting have you already tried from the article below about the 520 error you’re getting ?
Anything in the configuration file of NodeJS being modified?
no, nothing has changed
