• The Desktop Client fails to authenticate the user.
• In the FSDCTray.log, you see errors indicating issues retrieving discovery cache files from the Policy Server:

• When testing with Fiddler (on admin-less agent), the server returns HTTP 504 Gateway Timeout and sends 0-byte response instead of discovery cache files.
  

Root Cause

The Desktop Client cannot retrieve authentication discovery cache files from the Policy Server. These files are required for initializing the login service.

Cache file locations:

• C:\ProgramData\Seclore\FileSecure\Desktop Client\<username>\Discovery\AuthDiscovery
• C:\ProgramData\Seclore\FileSecure\Desktop Client\administrator\Discovery\PolicyServerDiscovery

Workaround

Copy the missing cache files from a working machine to the same directories on the non-working machine
