Users are randomly encountering a 400 BadRequest error when attempting to log in to IFS Cloud 23R1. This error prevents affected users from successfully logging in. The environment consists of a cluster configuration with three application servers, and client terminals connect to the application gateway during login.
The error is random and temporary, occurring inconsistently across different devices and users; it may stop on one device and start on another, even among terminals with identical settings on the same network, and while it sometimes resolves itself after a wait, clearing the browser cache does not help, with no correlation to the time of day.
