I was having trouble with a Tenvis IP camera model JPT3815W updating it’s built in DDNS. For the record my original DDNS that is on the sticker must have expired.  I was doing everything right as it was working fine and then all of a sudden one day it fails to update my IP. If any one else has a similar problem just ask for a new DDNS user and pass and change it. First to make sure go to google and type “my ip” then take that...
