[rules-users] Unexpected, Unclear, Unperiodic error

Are the admin module and user module running in the same box? Can you
access the package's URL from user's side? The error is clear, the kagent
is getting a HTTP-502 error when it tries to read the package binary. Maybe
a network configuration issue?
