Today I migrate from ZCS 5.0.19 32 bit to versión 8.0.2 64 bit. Everything went fine, the only thing is that when I want to see the server queue status I get the error:

Se ha detectado un error del servidor
Mensaje: system failure: exception during auth {RemoteManager: mail.xxxxx.com->zimbra@mail.xxxxx.com:22} Código de error: service.FAILURE Method: [unknown] Detalles:soap:Receiver

It's like there is a problem with the zimbra account ?
