Frequent 525 and 520 errors

This morning my site began experience 525 and 520 errors (and very infrequent 524). As far as I can tell, nothing changed on the server side. The errors were intermittent and didn’t seem to follow any pattern or correlate to behaviors/load on the server.

I’ve since paused cloudflare entirely for the site, which I’ve verified by checking the certificates presented to the browser (letsencrypt vs cloudflare CA) and the domains appear to be working fine with cloudflare out of the way.

Are you on KnownHost?

I am not. I use an NFO VDS.
