I self host a bunch of things on my home network and since i dont have a static ip i use duckdns so i can access it via the greater web and set up ssl etc. Works great for my laptop and other people but on my phone where im using rethink dns to filter web access the duckdns domain doeant resolve (its not getting blocked it just not resolving at all). It resolves on cloudflare and ive set that as the fallback for rethink but still doesnt resolve any advice/help would be greatly appreciated.
