3CX FQDN not resolving

[Sebastian H]

I'm having an issue where the 3CX FQDN is not resolving. It's only happening on one of my 8 current systems. This is the 3rd time this week it's happened and the 2nd time today. The fix which I read about on this forum is to change the IP on the system to dynamic, then change it back to static and ususlly that fixes the issue. However, that did not work this time. Not sure why this is happening but now that they've removed local ip for provisioning, all the phones in the building are down. Why does this keep happening with only one FQDN and how can I stop it from happening?

Never mind. I figured out the issue. I had a computer that I used to create the original config for this system, pulled the backup, powered off the PC but never uninstalled 3CX. Today there was a power outage in the office so the PC turned on again and started pulling the FQDN to the IP it was on. Now if I can just get 3CX dns to update to the correct IP quicker, it would be all good.
