I just received a DNS record from the AD guys and am trying to change the website URL of my jamf Pro. We are using 10.9 and this is a development instance with no devices enrolled....yet. I went into Global Management then Jamf Pro URL. I enter what we want the URL to be https://dnsname.companyname.net. I tried restarting the server as well, however we are still unable to connect to the new URL and can still connect to the old IP. What am I missing here?
Do an nslookup with the new DNS name to make sure the DNS record is actually there and is pointing to the correct IP address.
Are they making you change your IP address in addition to DNS name? If so you'd need to make sure the server itself (in the OS) is configured to use the new IP address.
As far as I know, when you change your Jamf Pro URL inside of Jamf Settings, all you're doing is changing what URL your managed devices use when doing MDM actions for devices enrolled after changing the URL there. It still has to resolve in DNS and on the network first.
