3645 stopped working after 3 years

[danfront]

I have deployed around 20 3645s using an AVPP and today the phones stopped working. They can connect to the WIFI network, they allow you to enter the extension and password, when then they just reboot and get stuck on trying to reach the PBX CLAN IP address that is defined in DHCP option.

I've logged into the AVPP and the config is still correct. Any ideas?
