After upgrading to 7.4.5 I was going to push out a small change to all of my controllers but discovered that it wasn't working.
Here's what I've done troubleshooting this issue so far...
1. Recreated the changes and re-released it.
2. I can ping from the Airwave Server to the Controllers and vice versa
3. Ping from the local controllers to the Master and the backup Master, no replies.
4. Checked with my WAN manager to make sure he didn't make any changes to the school's ACLs
5. Looked at the Debug log on one of the controllers and it is deplaying the following message.
"Cannot heartbeat with the master"
6. I looked this error up on Airheads and found a message thread that Colin suggests to enter the following...
"show datapath session table " Check to see if that output contains UDP 4500 traffic" YES IT DOES
"show crypto ipsec sa" "No active IPSEC SA"
7. I reentered the ipSEC Key on both the controller and the master and that didn't work.
8. I followed the instructions to initiate the debug logging...
logging level debugging security process aaa
logging level debugging security subcat ike
logging level debugging security process authmgr
logging level debugging security process crypto Results is attached
