Problem with tado controller

Hi I recently moved in to a new home with a tado system installed and all was working fine with the smart controller until recently when I got my broadband connected and decided to use the app with my phone.
Since then I have lost all control with the heating the water heats up but other than that I now cannot control anything even with the smart thermostat.
I have tried resetting all devices and everything looks like it is connected.
The extension kit shows a breathing pattern on the led. And the thermostat controller shows a linked chain, the internet bridge however is still flashing the paring led.
