What is HTTP 405 Method Not Allowed Error?

HTTP 405 Method Not Allowed Error means that when your browser tries visiting a webpage or API endpoint or other resource whose server handles it in a way different from what it expects, then an error message like 405 Method Not Allowed is sent back. That is, because of the language barrier no communication will take place between the two parties in case of exchanging with the server.

Example Scenario: For instance, picture yourself trying to open a login page on a website as mentioned above. In order to load the login form your browser will send a GET request. However, if the server has been configured to accept only POST requests for logins you will get the 405 error.

Here’s a breakdown of the key components

• HTTP Methods: These are verbs that specify the desired action on a resource. Common methods include:
  • GET: Retrieves data from a server.
  • POST: Submits data to a server (e.g., filling out a form).
  • PUT: Updates existing data on a server.
  • DELETE: Deletes data from a server.
  • PATCH: Makes partial modifications to data on a server.
• Server Configuration: The server specifies the methods that can be allowed for specific resources. Security considerations, resource type, and application logic can all form the basis of this configuration.

Communication on the internet is done through HTTP. This ensures that it is most useful to users by defining the paths on the network over which it travels and how data moves between web browsers and servers. Miscommunications can still happen but that does not mean that everything has gone wrong leading to error messages. One of these errors is the HTTP 405 Method Not Allowed error, with users getting frustrated on a daily basis.

In this post, we will look at 405 errors more closely; their causes, potential fixes, and ways to prevent them. After going through all these instructions carefully, you can be able to identify as well as troubleshoot the same problem independently thus avoiding breaking down of connection between your web browser with the servers.
