Problema "Host Error"

Ciao, sto riscontrando un problema di "Host Error" pertanto da più di un'ora il mio forum non è raggiungibile. Ho controllato lo spazio hosting ed ho consumato soltanto il 15%. Il problema potrebbe essere riconducibile al CloudFlare? Devo fare io qualcosa oppure il problema sarà risolto dal Provaider? Grazie.

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.
