Hi,
I am experiencing the same issues with the Technomate TM-NVR app not working recently.
I checked on Google Play store and there is also a recent review saying that the app is no longer connecting also.
I used to use it every day to check on the cameras but hasn't worked for just over 1 week now.
Tried calling Technomate offices in London but they are closed atm until the new year. Im going to try them again then to see whats going on.
Regards,
