Problem when enrolling the RA

Hi,

   When enrolling the RA with the CA, I got the error dialog
"Unknown Message 0x10054", and then the CA window disappeared
without any message.
Here is the RA's log:

!  Entering POST timer
!  Creating an RA enrollment record
!  Allocated object-id 1 for this request
!  Enrolling RA 1
!  Found my self-signed certificate
!  Obtaining KID
!  Generating nonce

!  Message protected with DSA w/ SHA1
!  Returing 0 from generate_pkix_message[2]
!  Sending message of type 0 to pkix://140.113.241.33:829
x Send failed status = 10054 (len 0)


Could someone help me please?
