We have a number of Cisco AIR-CAP1702I-E-K9 APs and a virtual WLC (v8.0.140).  Four of the APs talk to the WLC ok, but the remaining two won't connect with the following error:

Oct  5 15:48:06.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.50.50.119 peer_port: 5246
*Oct  5 15:48:35.999: DTLS_CLIENT_ERROR: ../capwap/base_capwap/dtls/base_capwap_dtls_connection_db.c:2214 Max retransmission count reached for Connection 0x7C58280!

One of them was working previously but had a factory reset; the other is out of the box.  How can we make them connect to the WLC to be managed?
