Communications failure with the Cisco Smart License Utility (CSLU)

loosing my tether with this,

 

can't get a 4451 to talk to the CSLU.

 

there's nothing special in the config, no vrfs etc, default route pointing out to the internet. There is no firewall blocking anything either. I can ping a hostname fine.

 

SIPS#ping tools.cisco.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 72.163.4.38, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 123/123/125 ms
SIP#

 

but when I force a license sync I get this

 

SIP#license smart sync all
SIP#
Jun 15 15:58:12.228: %SMART_LIC-3-COMM_FAILED: Communications failure with the Cisco Smart License Utility (CSLU) : Unable to resolve server hostname/domain name
SIP#

 

running a debug on call-home I get no output at all.

 

if I debug on DNS I see queries for the ping but absolutely nothing for the license sync.

 

running on the latest gold release Amsterdam 17.03
