Capt,
I tried your container but get the following error:
Starting DDClient
WARNING: unable to determine IP address
Starting DDClient
WARNING: file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword 'ip' = ''
My ddclient.conf file is pretty basic:
protocol=namecheap
server=dynamicdns.park-your-domain.com
login=***.com
password=********
vpn
Am I missing anything?
