Tado Thermostat Internet Bridge disconnected and won't connect

Options

Hey all, I had a major issue with my internet and had to reboot all routers and mesh points.

However, I've only just noticed that the bridge is flashing for the router. I tried a different cable and port and it's still flashing.


Do I need to do a factory restart and add all 14 thermostats in again? Or is there a way for it to find data given that its ethernet only and has no wifi? Thanks.
