Contact your hosting provider letting them know your web server is not completing requests. An Error 522 means that the request was able to connect to your web server, but that the request didn’t finish. The most likely cause is that something on your server is hogging resources.

We don’t maintain the servers, so we don’t have the full picture on why certain issues happen. And the company that does know typically isn’t that proactive in informing us, which is why we sometimes have to find out pretty late.
I also wish we’d have a more complete picture sooner. But this is just how it works.
But you also said that your website was down “since a couple of days”. Our servers haven’t been down for multiple days. So I’m not sure what issue you’re having, because it might not be an outage on our end.
I just checked your website and it’s not using our hosting, so I cannot check it right now.
