How to Solve "Error Code 400" Login Failure
This article explains how to solve login failures due to "Error Code: 400" and/or "Error Code: 10002".
Technical Background
Starting in March 2024, we have integrated the different accounts of users using Marvelous Designer, CLO-SET, and CONNECT into one, and the Marvelous Designer have changed the login via CLO-SET webpage instead of entering ID and password in the login window. This policy will be applied from Marvelous Designer version 2024.0, and previously released Marvelous Designer 7.x or 6.x versions will run by entering ID and password. After the account integration, if the previously-used-user-login-information and the newly-integrated-user-information do not match, or if old-user-information is stored in the web browser being used, the Marvelous Designer login will fail and an error message will be displayed.
Problem Situations
- Launched Marvelous Designer, but get an error message instead of logging in.
- Successfully logged in to CLO-SET on a web browser, but get an error message.
