How to Fix DoorDash Status Code 400 (Bad Request)
HTTP status codes (400) in DoorDash and Dasher may appear in several different forms. “HTTP 400 Bad Request,” “Request failed with status code 400,” “HTTP error 400,” and “400 Bad Request” are common variants of the error. This post highlights factors responsible for DoorDash error code 400 and possible solutions.
“400 status codes” are client-side errors that prevent DoorDash from processing a user’s request. The problem could be your internet connection, outdated operating system, browser malfunction, corrupt app files, etc. Signing in with incorrect account details (email or password) can also prompt these errors.
Before trying the recommendations below, verify that your internet connection is working correctly. Visit any website in your web browser or open internet-dependent apps and check if they work. Reboot your Wi-Fi router, disable VPN connections, or contact your Internet Service Provider (ISP) if your internet isn’t working.
Otherwise, try the following troubleshooting tricks if your device has internet access, but DoorDash displays the error code.
Force Close and Reopen Doordash
The problem could be due to temporary software glitches in the app. Some DoorDash and Dasher users stopped the “400 Bad Request” error by force-stopping the app(s).
Long-press the DoorDash app icon and tap the info icon. Select Force Stop and select OK on the confirmation.
For iPhones, open the App Switcher—double-press the Home button or swipe up from the bottom of the screen. Swipe up on the DoorDash or Dasher app preview to close it.
