TLS failed with atcp error certificate verify failed
Has anyone encountered this issue? The TLS negotiation gets as far as Client Hello, Server Hello, "Certificate, Server Key Exchange, Server Hello Done". Then the SBC terminates the tcp session. The log.atcpd file has:
Jun 20 17:42:59.047 [MINOR] (1) SSL_accept failed
Jun 20 17:42:59.047 [MINOR] (1) OpenSSL Error14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed:s3_clnt.c:1315

does anyone know either where to look or how to get any more information about the error?
