Taking too long to join Controller

[nawas]

I'm replacing 2106 controllers with Cisco 2112 and 2125. During the replacement APs fail to backup controller but then they never go to their own controller, I had to wait more than 2 hours before it joined the controller, I have never seen this before but in the previous two deployment it has taken this long.

1. Debug lwapp client events

And following on Controller:

Debug lwapp errors enable

Debug lwapp client events

#replace lwapp with capwap if u r using capwap code
