Hi there Queenvic
Thank you so much for your post and welcome to the community forums, it's great to have you here.
I am so sorry that you have faced this issue with your Hub, I have taken a look and cannot see any outages etc on our side that would be causing this.
Are you able to try a pin hole reset? To do this push a pen etc into the reset hole at the back of the Hub and hold in for 60 seconds. This will cause a full factory reset so if you have changed any Hub settings such as the password they will revert to the original but you can change these back afterwards.
