I have recently upgraded from 6.5.x to 6.6.x and I am now encountering openSSL communication errors between my Deployment Server and Universal Forwarder.
SSL encryption is configured for DS to FWD and FWD to IDX. The configuration was working fine until we upgraded from 6.5 to 6.6.1 at this point the communication from the DS to the FWD stopped working. No changes were made to the certificates.
The communication between FWD to IDX via 9998 is still working fine but FWD to Deployment Server does not work with the verifyServerCert = true enabled in the server.conf of the DS configuration.
We receive the following error message CA: WARN SSLCommon - Received fatal SSL3 alert. ssl_state='SSLv3 read server certificate B', alert_description='unknown CA'.
