When do you move the server, as it can take 6hrs for the fqdn to populate is using std or pro license - 5 or 6 mins for enterprise.

do you use your own DNS server ? if so could it be something stay set with previous IP

Did you completely stopped or removed your Azure instance? no chance it may be always online and pollute your new one on DO ?

Check once more on azure first, then check in 3CX console if this is DO ip set and not old from Azure

it seems something went wrong with DNS update linked to your FQDN

 

[MrUn1x]

it seems something went wrong with DNS update linked to your FQDN

so is there anyway to change FQDN without reinstall the server and be noted that is standard license .

Done sent

if you go on 3cx console, settings, parameters
in search field type in : IP

Do you see somewhere your old public IP from Azure ?
