Hello Ralucageo
Sorry to hear of the hub issues and the red light, we appreciate you taking the time to raise this via the forums and welcome to the community.
Please can you try this for me:
• Turn the power switch off on the back of the Hub.
• Ensure the Hub is upright, in a well-ventilated location and out of direct sunlight, if possible.
• Switch the hub back on at the power. The Hub should now operate normally.
Please report back with the result.
Thanks
Rob
