Syslog server showing: Fatal error: : unable to send NTP packet to ::ffff:172.23.254.89.

[rraineri]

I am working o a case where a syslog server is showing the following log:

"DW2WLC01.SYS: *sntpReceiveTask: #SNTP-3-FATAL_ERROR_OCCURED: sntp_main.c:233 Fatal error: : unable to send NTP packet to ::ffff:172.23.254.89."

I have been doing reasearch around but I have not found cases related or log explanations, the only thing I found related is bug CSCug11763. However this bug doesn't offer further details.

5508 WLC is running 7.6.100

Anyone has any idea about the possible meanings of that log?

Hi, Please try to disable IPv6 and then check it:

(WLC) >config ipv6 disable

If still same error comes then  please raise a TAC case.

Hi,

IPV6 is already disable, the issue stills the same. Any other idea?
