using duckdns to access netdata

Setting up my first cloud server and working on configuring netdata. I was hoping to set up access through duckdns so that when my local ip changes, it would update the netdata configuration automatically. I’ve got this in the conf file, but I haven’t been able to get it to work. I was hoping I might find a pointer here.

    run as user = netdata
    web files owner = root
    web files group = netdata

    bind to =
    default port = 19999
    allow connections from =
