400 bad request

The400 is an HTTP status code that tells the client that it sent an abnormal request. 400 pages are pages that are returned to the user interface with a 400 prompt when a user opens a web page. It means that the domain name of the page you visited does not exist or the request is incorrect. It is mainly divided into two types.

1. The semantics is incorrect and the current request cannot be understood by the server. The client should not submit this request repeatedly unless it is modified.

2. The request parameters are incorrect.

There are two main forms of 400:

1. Bad request means "wrong request"

2. Invalid hostname means "domain name that does not exist".

Such words usually appear only on Windows hosts, and different error messages are displayed in the case of Linux hosts. The reason for this error in bad request invalid hostname is that a domain name is bound to a host, but the host is not bound to that domain name, so IIS returns this prompt. What should I do when I encounter this problem? First of all, the solution is to Ping the domain name to see if it is resolved to the IP where the space is located. If so, go to the space management panel to see if your domain name is bound. If so, it is definitely the problem of the space provider. To solve this problem, you can only find the space provider to bind your domain name. If you have this permission, you can bind the domain name yourself.

HTTP status code classification

The server receives the request and requires the requester to continue to perform the operation. 2 successfully, the operation is successfully received and the 3 requests * redirection is processed successfully, further operations are required to complete the request 4 requests * client error, the request contains a syntax error or cannot complete the request 5 requests * server error, the server encountered an error in the process of processing the request
