Hi Terri,

Have you looked over this howto:
https://www.digitalocean.com/community/tutorials/how-to-install-the-ajenti-control-panel-and-ajenti-v-on-ubuntu-14-04 It shows how to setup the panel for Ajenti

if you want just to create a subdomain create a new A record, if you want panel.mydomain.com for example create an A record with the first section as ‘subdomain’ and the second section as the IP address you want to target (your droplet)

Hello, I wrote that tutorial! :)

You tried browsing to https://panel.example.com:8000 correct?

If you did, make sure you created the panel subdomain in DigitalOcean, it was one of the prerequisites. If you didn’t read: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-host-name-with-digitalocean

If you’ve already done that, you can try setting the hostname for Ajenti within the Ajenti control panel. Go to your Ajenti control panel through either your IP or whatever domain you have set up, and in the sidebar, press Configure. Under the second section (HTTP Server) change whatever is in the Host text box to panel.example.com. Then click the Save button at the bottom of the screen, and then click the Restart button at the bottom of the screen.

I hope that helps!
