Getting Error 520 whenever I try to update a Wordpress post

Dear CF community,

I have been running into persistent issues trying to use Cloudflare with a domain running Wordpress.

At my host’s request I have tried every possible option in the SSL settings. It simply changes the Error ID that I receive.

At the moment, it’s showing up Error 520. They have run out of ideas.

The error seems to trigger whenever I attempt to upload a file to the media library. Strangely enough, the frontend is unaffected during this period — only the backend redirects to the CF error page.

Any idea what could be causing this?

Any 5xx errors should show up in your server logs. Here are some suggestions:
