About three days ago, my site started to display error 520 in a strangely random way. I use a VPS server on Hostgator for my wordpress site.
I have made absolutely no changes to any kind of configuration on my server, it’s been a long time since I last did. As I said, the error just started to happen out of nowhere.
I can’t purposely reproduce the error. I have already opened 150 pages on my website quickly, one after the other, without the error appearing. And sometimes, I’m using my site normally, I open a page and the error comes up.
The error doesn’t happen with a high frequency, on the contrary, it’s totally possible to browse my site without the experience being harmed by the error, because as I said, it appears very occasionally.
I’ve already checked the cpanel error log, and there apparently isn’t showing anything about the problem. I’ve been using cloudflare for two years now, and it’s the first time I’ve been dealing with it.
It is important to mention that as soon as the page is refreshed, the error disappears. After refreshing the page, the site continues to function normally, with good performance and no slowdown issues.
