When I upgraded from v14 to v15, I used my own FQDN - 3cx.mycompany.com (as I already had the DNS set up and it seemed easier not to change everything). I purchased a certificate from GoDaddy. On the Network Settings->FQDN page in the management console, the FQDN is shown correctly as my private domain 3cx.mycompany.com. But in the partner portal at erp.3cx.com, it shows as a 3cx domain as 3cxmycompany.3cx.eu. The FQDN IP shows correctly as my static IP. I tried releasing the FQDN inside the portal, but it just seemed to reattach itself. Is this normal behavior? If not, can it be fixed?
