Thank you very much, however, now, I am facing the problem of Timed Out(522 Error), is it the problem of the server side? It changes to 524 Error(A timeout occurred) sometime. Oh, it is solved, but a new problem is appeared... (1040) notconnect it might be the sql database connect problem, also cpanel login shows "Connection Timed Out, please try again" A network error occurred while sending your login request. Please try again. If this condition persists, contact your network service provider. OK, thank you, everything work normally now, I will mark this as solved.
