H71 Error, Heat link not working

Countryescape

I have 2 Nest thermostats - One is working perfectly well, but this has been replaced late last year as this failed and was automatically replaced by BOXT. 

Now my downstairs link has stopped working with the code H71 and there is no light on the link so unable to reset.

They were originally installed in 2021.  

Can someone from Nest/Goggle let me know how this can be resolved please as I'm unable to control heating?  Do I need a new Link? 

Thanks
