Logging onto my freePBX this morning shows unregistered, prompted to activate, was working fine yesterday afternoon.
Activation fails with my Deployment ID - claims ID already licensed to different host 
Can you Reset Hardware Lock for that Deployment ID in the Sangoma Portal? Do that and then try activating again.
Great, thank you, resolved.
No idea why this happened, I can’t spot any problem.
Learned something new today.
Two days later system deactivated again 
No more resets available.
I do not know what causes this action, where do I look for any clues?
Hi, Please make sure that time date is on sometimes licensing fail2 if time is off, consider checking the asterisk & httpd logs make sure one more thing that your pbx is reaching sangoma licensing servers.
