provisioning files 404

[MSchilder]

Hello

Suddenly our 3cx pbx doesnt provide the provisioning files anymore and thus none of my phones are not registering anymore. I have no idea what causes this.
Anybody a idea on how to tackle this? The system runs in OVH and i didnt touch the system for weeks. Its running on the latest build

Once a phone is provisioned, in theory, unless you did a factory reset, it would be happy to continue on without being re-provisioned. Something else must be going on. What version are you using? How are the sets working? SBC, VPN, STUN? Does the 3Cx Activity Log provide any clues at to what may be happening? Failed registration attempts? Can you pin-point a time/date (logs) when this began? Anything else happen at that time? Do you use a dynamic public IP?

Hi @MSchilder

In addition to what @leejor suggested, also check the IP Blacklist in case the whole site IP was banned
