I am trying to setup dynamic DNS using DuckDNS. I have setup the DuckDNS docker in OMV and created my account on DuckDNS but it keeps on updating to the wrong IP address.
This does not seem to be something specific to DuckDNS as i have run several IP commands in Shell in a Box (curl api.ipify.org , curl checkip.dyndns.org, curl bot.whatismyipaddress.com) all of which get the same IP address that DuckDNS is using.
When I run these same commands on another machine on my network I get a different IP address which i'm pretty sure is the correct one as when I browse to it i get to my router login screen.
Any ideas on how to fix this?
