Hi Alzibiff,
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 connecting to the Connect App. In order for the App to find your hub, you need to ensure you are connected to the WiFi on your device. Please also ensure the app is up to date as is the device your're using.
The first thing to try, after ensuring the above, is a pin hole reset on the hub. This will be reset the hub and should allow the Connect App to locate it. Please try this and let us know how it goes.
If you're still having an issue after the pin hole reset, please expand further on the issues you're having in terms of the error message and what you were trying to do when it came up.
Many thanks,
