Solved Deskphones losts during the night

[AWS2P]

Hi,
on a V18.939 on premise PBX, this morning i got deskphones not registred (not all) . They are all on same flat LAN
Of course during the last night I did change nothing on pbx settings, IPs of the phones are not Blacklisted

I tried to reprovision unsuccesfully after phones reboot and pbx reboot
Provisioning file are generated successfully


In 3CX admin console phones are in bold, like they'd never been assigned to an extension and trying to assign change nothing.


Any idea on what to check or do ?

My bad, I found what did the mess. Yesterday I set a different DNS resolver for test and I thought i did reverse to set the previous one. But unfortunatelly i probably miss or forgot to save something and the value stay with the DNS changed.

So I did change on DHCP server and reset all and now phones are back.
Sorry for my useless post and question.
You can delete it or at least close it as fixed
