Can you look at your server’s error log files? Chances are the admin area has an error that’s causing apache or your web server itself to crash. Might also be rate-limited or blocked by your host.

Ya that’s all issues with the code you have deployed on Wordpress. Mainly your theme:

I recommend contacting your host about fixing this, it’s a little outside of the scope of this forum.

I change my theme, for the Twenty Nineteen, and same error 520

Again you should probably contact your web host, or debug your error logs. Fixing PHP errors is a little outside what this forum is geared towards.

But it’s a Cloudflare error, not a web host error ?

No, Cloudflare returns the error given to it by the server. It is a server issue. Community Tip - Fixing Error 520: Web server is returning an unknown error
