I have WLC 4402 soft 18.104.22.168 with AP 1242g
If I diconnect the ethernet cable of an an AP form 5 minute, and then reconnect it, the AP could not join anymore.
The message every one minute on the AP is:
*Oct 14 07:36:55.067: %CAPWAP-3-ERRORLOG: Go join a capwap controller
*Oct 14 07:36:55.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 172.28.145.5 peer_port: 5246
*Oct 14 07:37:09.000: DTLS_CLIENT_ERROR: ../dtls/dtls_connection_db.c:2013 Max retransmission count reached!
The only way to overcome this pb is to reload the AP.
Have you got an idea ?
