Epmp 1000 all of a sudden can not connect to elevate license server

We had a 2.4 epmp 1000 AP reboot last night, and now for some reason I can not get it to connect to the elevate license server. In the system log it says this: server_connect: failed to connect serve r cambiumnetworksltd.prod.sentinelcloud.com

Its connect to the CNmaestro just fine.

Any ideas why it can not reach the elevate license server?

What software version are you running? I think recent versions of software should include an error code in the system log.
