The 400 Bad Request error is an HTTP status code that indicates that the request you sent to the website server, often something as simple as a request to load a web page, was incorrect or corrupted in some way and the server could not understand the request.
How to Fix a 400 Bad Request Error
Check for errors in the URL. The most common reason for a 400 Bad Request error is that the URL was mistyped or the link that was clicked points to a malformed URL with a specific type of error in it, such as a syntax problem.
Clear your browser cookies, especially if you are getting a Bad Request error with a Google service. Many sites will report a 400 error when a cookie being read is corrupt or too old.
Clear your browser’s cache. A cached but corrupt copy of the web page you’re trying to access could be the source of the problem that’s giving you the 400 error. Clearing your cache probably won’t fix most 400 bad request issues, but it’s quick and easy and worth a try.
