were invalid for whatever reason (entered incorrectly, user ID suspended etc.). Fixing 401 errors - general Each Web Server manages user authentication in its own way. A security officer (e.g. a Web Master) at the site typically decides which users are allowed to access the URL. This person then uses Web server software to set up those users and their passwords. So if you need to access error code 401 ffxiv the URL (or you forgot your user ID or password), only the security officer at that site can help you. Refer any security issues direct to them. If you think that the URL Web page *should* be accessible to all and sundry on the Internet, then a 401 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 the Web page. If this type of browser check indicates no authority problems, then it is possible that the 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 401 erro

It's possible that the 401 Unauthorized error appeared because the URL was typed incorrectly or the link that was clicked on points to the wrong URL - one that is for authorized users only.If you're sure the URL is valid, visit the website's main page and look for a link that says Login or Secure Access.

If you don't have credentials, follow the instructions provided on the website for setting up an account.If you're sure the page you're trying to reach shouldn't need authorization, the 401 Unauthorized error message may be a mistake. At that point, it's probably best to contact the webmaster or other website contact and inform them of the problem.

The answers below are ridiculously all over the map. It seems that the correct answer is undefined for non-HTTP authentication. –Joe Lapp Jun 7 at 19:30 add a comment| 11 Answers 11 active oldest votes up vote 1675 down vote accepted A clear explanation from Daniel Irvine: There's a problem with 401 Unauthorized, the HTTP status code for authentication errors. And that’s just it: it’s for authentication, not authorization. Receiving a 401 response is the server telling you, “you aren’t authenticated–either not authenticated at all or authenticated incorrectly–but please reauthenticate and try again.” To help you out, it will always include a WWW-Authenticate header that describes how to authenticate. This is a response generally returned by your web server, not your web application. It’s also something very temporary; the server is asking you to try again. So, for authorization I use the 403 Forbidden response. It’s permanent, it’s tied to my application logic, and it’s a more concrete response than a 401. Receiving a 403 response is the server telling you, “I’m sorry. I know who you are–I believe who you say you are–but you just don’t have permission to access this resource. Maybe if you ask the system admi
while surfing internet that “401 Authorization Required”, which is also defined as HTTP Error 401 . Now before going to the Problems & Solutions part let’s take a look upon it. HTTP means Hyper Text Transfer Protocol, which is an application protocol for collaborative, distributed and hypermedia information system. In short it generally runs the internet in a well manner. HTTP has different source code. Now coming back to our topic, if we see "401 Authorization Required" message in our web browser that means we first have to login i.e. have to give user ID and password to access the specific web page. If we already gave the credentials and still after that it shows the message, it means we have given wrong credentials. Sometimes it can happen like this also: we gave the credentials in our office computer and it showed the web page, but when we tried it with exact same credentials in some other place it showed the message "401 Authorization Required". It happened because that specific web page can only be seen on some particular computers. Your current computer’s address is not authorised to see the web page. More on HTTP Error 401 there are some specifications on it. Likewise: HTTP 401.1: Denied by invalid user credentials HTTP 401.2: Denied by server configuration HTTP 401.3: Denied by resource ACL HTTP 401.4: Denied by custom ISAPI filter HTTP 401.5: Denied by custom ISAPI/CGI Web application Problems When we encounter HTTP Error 401, we can’t see the specific web page. If we are looking for a file to be downloaded then it can’t be downloaded until the problem is resolved. Solutions First of all we have to check whether the URL (Universal Resource Locator) is correct or not. If the URL is wrong then we have to type the correct URL and try again. Sometimes if we are going to a particular URL via some link then there is a possibility that the link is wrong. So we have to take care of that also. If the URL is correct and still we can’t access the page then might be we don’t have permission to access the web page. In this context if we are authorised to see the page then we have to find the login area and have to give correct credentials. If the site we are visiting doesn’t require any authorization and still it’s showing the message then there mus
