Understanding HTTP status code 401
While browsing the internet, you might see the following error message: “HTTP 401.” This means you cannot view that particular webpage or any other resource you are trying to access. This error usually comes up when there is an attempt to continue with the actions that require log-in or other forms of authorization. It is like being given a key to open a locked door only to be told the door leads to a room where you cannot enter. The server says, “Sorry you cannot go there.”
This status code does not appear for users, especially as an HTTP 401 error. One possible factor could be due to an incorrect username or password. It can be that any of these credentials are wrong because of some mistyping or that the user had parents correct. Another reason could be that the user tries to log in after a long time. Most login sessions have a specific stalk, especially when the user has no action. Most users get logged out after such a duration, which is set in the system, and if it has not been taken, the login process may have to be repeated.
On occasion, the problem of HTTP 401 error may arise due to issues on the server side. There could be a bug in the authentication system, or the server may be down. Otherwise, the error may implicate the web browser or the Internet connection. For example, the cache and the cookies in the web browser might have been corrupted, thus making it impossible to complete the authentication process. In a like fashion, an intermittent Internet connection problem could also result in being unable to access the said web page.
Common Causes of HTTP 401 Errors
There are several reasons why, from time to time, an error number 401 may occur:
Incorrect Credentials:
One of the most common causes of HTTP 401 errors is entering inaccurate credentials. This could be due to a comfort typo, or you may not remember the correct login or password characters. Pay attention, and take the time to enter your credentials; in most cases, people make typos.
Expired Session:
While every user’s session is logged in to the website, there is usually a fixed amount of time for such user’s activity to be idled. When too much time has passed without engaging you, your login session will time out, and the ‘HTTP Error 401’ message will be displayed. This is usually enforced to ensure that no one attempts to log in to your account, irrespective of mode.
Server-Side Issues:
In some scenarios, the fault does not lie with the user but with the server responsible for the authentication authentication process. The server may be malfunctioning due to a problem with its software or hardware, and in some cases, the situation may be out of control.
Browser or Network Problems:
The HTTP 401 error code can also be accompanied by issues related to your browser or a malfunctioning internet connection. Your browser’s cache or cookies might be corrupted, hurting the log-on mechanism. Similarly, if there is a brief interruption in the internet connection, it will also cause difficulty locating the site.
Types of Authentication Methods
There are different methods used for Authentication on the web:
Basic Authentication:
This is the most basic form of Authentication whereby a user sends their login credentials in a non-encrypted text. Basic Authentication is easy to set up but is the least secure method because login information is sent in an open text format, which is likely to be intercepted.
Digest Authentication:
| Aspect | Details |
|---|---|
| Method | Secure method |
| Process | Hashes credentials before sending them |
| Security Benefit | Avoids sending plaintext credentials, reducing threats from surveillance attacks |
| Key Factor | Digest Authentication decisions depend on the availability of HTTP cookies |
Safe Access Framework:
A widespread mechanism type includes the granting of access to an API from the users by the user of the resource owner. OAuth makes it possible to allow third parties some limited access to information but does not allow for the provision of sensitive information like passwords. This method is typically employed with social networks and online services.
Token-Based Identification:
A process that incorporates using tokens to identify and grant permission to users. The server app usually generates such tokens and dispatches them to the concerned client. The requestor possesses the token and presents it alongside the request to the server. Token-based identification is typically applied by modern applications that utilize APIs for their operation as it is flexible and scalable.
How to Fix Unauthorized Error: Troubleshooting HTTP 401 Errors
Should you encounter the issue of HTTP 401 errors, here are some recommendations that can help you solve the problem:
Double-Check Credentials:
Before clicking the proceed button, it is essential to confirm whether you have accurately typed the username and corresponding password. Failure to log in can result from being careful with the credentials.
Clear Browser Cache and Cookies:
Sometimes, old or broken cache and cookies may cause errors when trying to authenticate. This is often the reason for HTTP 401 errors from confused browsers that require the cache and cookies to be wiped. To do this, go to your browser settings and scroll down until you find the option for browsing data deletion. According to the type of information you want to be cleared, choose and click on such options as “Cached images and files,” “Cookies and other site data,” and “Site data.” After that, hit the button labeled “Clear data.”
Try a Different Browser:
If clearing cache and cookies still does not work, you can always try visiting the website using a different browser. This is a good way of narrowing down the problem to whether it is related to your present browser or if it affects all browsers in general.
Check for Browser Extensions:
Some installed browser extensions can hinder Authentication in some instances. Turn off any new extensions and see if they make a difference.
Contact Website Support:
If the two or one above solutions do not work, try contacting the website’s support. They can help you with the specific problem and your account.
