My heatlink suddenly stopped working. It has no lights and I can't turn on my heating. The bolier has power and is heating the hot water Ok. The thermostat won't connect to the heatlink

Hi, I'm experiencing the same problem.
Our 3rd gen nest thermostat heatlink (UK-EU) version has stopped working:
-It is not supplying power to the thermostat (it works & charges independently via USB)
-LEDs on heat link are not powering on
-We have tried different sockets, all of them work but the heat link does not.
-no fuses related, no changes on the electrical system, no storms or anything that could have damaged the system
-Tried pressing the button for 30 sec several times: still no led on
-Nest was installed 11 months ago
Please, google Nest customer service, could you help with this issue?
Thank you very much
