i went through Polanskiman excellent tutorial and everything worked first time, thank you for that
after logging out i couldnt log in again, i was trying for ages with http://[yourdomain].duckdns.org:5000 or 5001
and https://[yourdomain].duckdns.org:5000 or 5001, ive opend my ports from 5000 to 5001, as in the tutorial
i uninstalled and reinstalled DS file from my mobile but that didnt do anything
i eventually tried [yourdomain].duckdns.org with no http:// or https:// and no port number at the end
it signs in straight away, if i go back and sign in as https://[yourdomain].duckdns.org:5000 or 5001 it wont sign in
