7. Look at your server’s issues.

Look for any HTTP headers that aren’t legitimate.
Examine the app’s server-side logs to see what it performed, such as the sites it accessed, the servers it connected to, and the database results it provided.
Debug application or script code. Make a duplicate of the program to a local development computer before debugging so you can reproduce the identical situation that occurred before the 400 Bad Request error occurred.
