Issue/Introduction

Logging onto CSM through Microsoft Edge, get "UI Session Exception" and "Password exception has occurred", and "500 The call failed on the server; see server log for details", followed by "MMU1002E Your session is no longer valid. You will be logged out".  This has worked in the past, and works on Chrome.  Tried clearing cache, cookies and temp files, and cycling Edge, but issue remains.

Environment

Release : 6.0

Resolution

Remove and enable ALL cookies, not just from Broadcom in Edge.
