Does it keep saying that over and over again, or does it only say it a couple times?
It looks like it can find the controller and it can send syslog to it, but it cannot send papi (UDP 8211 or GRE protocol 47), which is needed to bring up wireless Virtual APs. If it is only a couple of times, it is an artifact of being down when the switch was down. if it is repeated, check to see if you have a firewall blocking UDP 8211 and GRE protocol 47.
