Hi Lucky71,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear you're having an issue with your hub showing a red light. As you've already tried the usual checks, and the issue still persists, I'd like to arrange a hub replacement for you and we need an engineer to come out to do this. I just need to confirm the address to move forward on this.
I've sent you a direct message to allow us to do this with you in a private space. If you're using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you're on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊
Thanks,
