Unfortunately,I don't have an answer for you.
Here is an explanation from cloudflare:
Error 520: Web server is returning an unknown error

I had that too but all seems well now.

It's a funky error code. Not specific to the point where it could definitively reflect server-side issues, when many may have the same error in the same time period. If if stops and just goes away, no harm, no foul.

Or

It might be indicative of a client-side problem, such as a corrupt operating system file. Sportster, you might use CCleaner and click its "registry" icon and then click "scan for issues". See if it picks up anything to be fixed.

That's a sever host problem, nothing you can do.

Cloudflare sits between the client and the server, and that page is telling you that your connection to Cloudflare is good, but Cloudflare to server is broken, and it doesnt know why.

Most likely the server went down.

Beware ccleaner. Their code base got hacked, and they've been distributing malware.

Well, you know the issues I've had with my machine, so anything is possible. It hasn't done it this evening, so maybe it was just a fluke.

If it doesn't occur regularly it's most likely a server-side issue, beyond your control. If so, don't sweat it.

It's definitely server side.
