Error 401: Not allowed: No access to the site

Anyone surfing the Internet, not only encountered interesting content but sometimes also error messages. Sometimes annoying for many: Not only can you not access the requested page, you do not know what the display status code really means. However, the meaning of the 401 error is quickly clarified: You do not have access to the requested page. Usually, the cause of the error is also found quickly. We explain how to fix the problem and how this error actually happens.

What does status 401 mean?

When you surf the Internet, there is communication between the client (your web browser) and the web server. Through HTTP, basic Internet protocol, browser and client exchange status code. You will not see a large portion of this status message while surfing the net, because if everything runs smoothly, they will not be displayed separately.

HTTP status codes are grouped into groups: The first three are among the groups that your browser typically does not display. All codes within 100 describe the ongoing requirements. Codes 200 through 226 indicate that the browser request was successful. However, those messages moved in the 300’s, diverting calls. However, what you will see over time is the error message: All status messages from the 500 range describe errors affecting the server side. Errors 400 to 499 In contrast, indicates problems affecting the customer.

So even at 401 is an HTTP code indicating an error with the client. “Client” may have different meanings in the sense of these error messages, because this only means that the case of communication approaches the web server. This may be the browser, but also the router or even the Internet provider, which connects to. However, in many cases, the internet users themselves have caused the error.

Sometimes you will get “401 Licensing Requests” instead of “401 Unauthorized”. Basically, both means that you do not have the rights to the requested site and you must log in first. If the web server is running Microsoft’s IIS, more specific status codes are usually displayed:

  • 401.1: Login failed.
  • 401.2: Login failed due to server configuration.
  • 401.3: The requested content was rejected by the Access Control List (ACL).
  • 401.4: Due to filter, authorization failed.
  • 401.5: Authorization failed due to ISAPI / CGI application.

In the best case, you will visit a specially designed error page that will tell you directly what you have to do.

How can you fix the 401 error?

In most cases, you can easily fix the 401 error: Affected websites have areas that are only unlocked after authorization. To call your desired website, you must enter your login data in the appropriate location. If you do not already have an account on the site, you must create an account and register with it. You will most likely find the hyperlink on the start page or in the header area. The error page will be displayed whenever you try to skip this login step and enter a link to the blocked page directly in the web browser.

So it can happen that the error message occurs if you follow an external link. If the page behind the link is in a password-protected area, your browser will most likely display Error 401. Then it’s best to go directly to the home page or try to switch to a new one. The next step in the directory structure of the site. So in example, next try It’s possible that upstream directories are available to you.

In any case, if you made an error by manually entering the browser, you should check the URL: You can only exchange one letter or one digit and thus have entered the protected area using the secret export.

An error can also occur if you have just logged in. Some sites will show you a 401 status code even if you entered the wrong login information. You may have entered the wrong password, username, or e-mail address. Return to a page and re-enter your data.

To err is human: So it can happen that you forget your access data. In this case, you must contact the webmaster. He can give you your username or reset your password. Many websites have also set up automated applications for this. You will be sent a link by e-mail allowing you to create a new password.

In some cases, you may have done everything right: you logged in correctly using the appropriate form, the entered data is correct, and you are greeted with a 401 error code. may have occurred at the server, but the system will interpret it as a 401 error. In such situations, this may also occur during other error codes, two proven approaches is likely in the past:

  • Just wait and reload the page: In most cases, the simplest solution is also most effective: Because site operators may be worried that their pages are available, they usually just wait for them to resolve. problem. Exercise a little patience and reload the site later. For your safety, first clear your cache and cookies so that your browser does not accidentally load the corrupted page from your internal storage.
  • Contact the webmaster: Of course, it’s likely that no one is aware of the problem – it could also be an error just in case. So, contact the site’s operator. Mostly you will find your e-mail address in the imprint. Even when it’s up to you, webmasters can help troubleshoot. Give your contact person as much information as possible about your system to get the solution as fast as possible.

If you can call the appropriate page in the past, so no password protection, you can still get the contents of the site with a small loop though error. Google creates cache for web pages, so it internally stores a temporary copy of the page. Just enter the Google search bar: http: //, instead of “” Enter the relevant URL to call the saved version. This may also be a bottom. A header informs you when to copy. Remember that you will not find the current information there and will only see a copy of a previous version of the page.

401 vs. 403: What is the difference?

The two status codes have very similar causes: While 401 means “Request for authorization,” the 403 status message usually contains the Prohibited Addendum: You are not authorized to access. As we have noted, the system would like to inform you at 401 that you need to register to access this site. So there should be a log for you at a higher level. This is not offered at 403. Webmasters are strictly prohibited from accessing this part of the site and have no opportunity to subscribe. Pages or directories are for internal use only and should not be accessed by external internet users.
