Lỗi 403 Forbiden của host vdeck

If you think that the Web URL *should* be accessible to all and sundry on the Internet and you have not recently changed anything fundamental in your Web site setup, then an 403 message indicates a deeper problem. The first thing you can do is check your URL via a Web browser. This browser should be running on a computer to which you have never previously identified yourself in any way, and you should avoid authentication (passwords etc.) that you have used previously. Ideally all this should be done over a completely different Internet connection to any you have used before (e.g. a different ISP dial-up connection). In short, you are trying to get the same behaviour a total stranger would get if they surfed the Internet to your Web page URL.

If this type of browser check indicates no authority problems, then it is possible that your Web server (or surrounding systems) have been configured to disallow certain patterns of HTTP traffic. In other words, HTTP communication from a well-known Web browser is allowed, but automated communication from other systems is rejected with an 403 error code. This is unusual, but may indicate a very defensive security policy around your Web server.
