Wireless Controller 2504 SNTP / NTP Errors

enewburn1 — Mon, 05 Jul 2021 11:45:25 GMT

I have a 2504 running 8.1.102.0 for some reason it is constantly generating a SNTP error that it is unable to send a NTP packet. It appears to be trying to send this to an all IPv6 address of "::"

I have disabled ipv6 on the Controller under global policy, wiped out my NTP servers and re configured as well as rebooted the controller.

Still the rrors persist - even if I wipe out ALL NTP servers and just go with local time

Any thoughts?

I've upgraded the Controller and APs to 8.1.131.0 (which was a good learning experience.) Unfortunately I still have the error
