I have a remote site with 2 AIR 2602i APs that were working up until a few days ago. One AP still connects fine but the second will not connect and keeps generating this error:
*spamApTask3: Sep 18 10:16:09.249: #DTLS-3-HANDSHAKE_FAILURE: openssl_dtls.c:687 Failed to complete DTLS handshake with peer 9702007188.8.131.52 for AP 97:cc:79:13b0b000:10507114:13040000
I have powered off and on both APs several times but still keep getting the same problem. Both APs are getting their config from DHCP and as part of that, a timesource. I can see traffic back and forth to/from both APs.
Thank you very much for the reply. I opened a TAC case and they identified an openssh bug in .120 and suggested to go to .130. This did solve the handshake issue, at least for now, but introduced a couple other issues that I may post about in another thread.
Thanks for the help.
