When you visit a website or even your website, your browser makes connections to the web server through a protocol called HTTP.
These connections transmit the data from the server to the web browser, which also includes information with different protocols and Web content. On some occasions, you may not be able to access the website normally, encountering different types of errors instead.
The status codes indicate the result of the response request from the HTTP server, consisting of 3 digits and divided into the following categories:
100 - 199: Informational status;
200 - 299: Success status;
300 - 399: Redirection status;
400 - 499: Error from client;
500 - 599: Error from server.
Most error codes cannot be viewed on the Internet. Error codes are displayed on the web page and result from failed requests.
Error 200 OK
The HTTP 200 OK code is received when the web server successfully processes the request and transmits the content to the browser without problems. Users will very rarely encounter this code on the screen since the codes are displayed when a certain problem is encountered.
Error 500 Internal Server Error
This error code appears when the web server received a valid request from a client but could not process it. They are triggered when the server encounters technical problems, such as too little disk space or a decrease in memory volume.
Error 502 Bad Gateway
The HTTP status code 502 Bad Gateway indicates that the web server you are requesting acts as a proxy for transmitting information from another server and receives an invalid response from it. Most of the time, this error is triggered when there are communication problems between the initial server and the proxy server.
Error 503 Service Unavailable
The HTTP 503 Service Unavailable error occurs when the web server does not process the request received from the client. It is possible that some web servers display the HTTP 503 error when the maximum limit imposed on the number of concurrent processes or excessive CPU usage is exceeded.
Error 301 Moved Permanently
The HTTP 301 Moved Permanently error shows that the URL accessed by the visitor has been moved to another location, using a process called HTTP redirection. This operation allows the visitor to make a new request to retrieve the content from the new location. Nowadays, all web browsers automatically follow HTTP 301 redirects, without the need for the visitor's intervention.
Error 400 Bad Request
The 400 Bad Request error type is most often a technical problem. In this context, the web server cannot correctly retrieve the request due to an invalid syntax.
Error 401 Not Authorized
This error code is triggered when the visitor requests a resource that is protected by the web server and has not been authenticated for access. In such situations, the client will first have to connect to the server with the help of a username and a password.
Error 404 Not Found
The HTTP 404 Not Found error indicates that the web server could not find the requested page or file.
This type of error occurs most frequently when the website administrator deletes a file without redirecting the address to a new location or visitors enter a wrong URL link in the browser.
In this case, users should check if the URL is correct or wait until the server administrators correct the redirection problem.
