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.
Due to the number of 520s being reported in similar circumstances, we are escalating the issue to Cloudflare Support. The original incident should have been resolved and your issue may well be unrelated.
We recommend checking these troubleshooting tips, if you haven’t already.
I am an administrator of a hosting provider, a Cloudflare partner and I have been getting constant complaints from our customers regarding the 520 error.
This happens randomly and we don’t find any information in the logs and all Cloudflare IPs are allowed in the firewall.
Our company and clients are located in Brazil.
Uma série de pessoas diferentes tem relatado há vários dias aqui no fórum problemas com o erro 520 aparecendo de forma aleatória, sem um padrão específico. Pelo que parece, é um problema do Cloudflare que está afetando usuários do plano gratuito (eu incluso).
Como você pode ver no comentário acima, o problema já foi escalado para o suporte há uns três/dois dias, devido a grande quantidade de pessoas que relataram o erro em circunstâncias similares.
As shared by @matteo if you are still see intermittent 520s after following the troubleshooting tips to fix the 520s, please reach out to Cloudflare support with the additional information in the post. You are welcome to share the ticket number with us on here.
