I am not an expert but it sounds like you can connect it to your phone wifi because you are close enough to it to connect via Bluetooth.
If thats true then maybe you can’t connect it to your home wifi because there is not s strong enough signal from the home wifi where you placed the b-hive. I had to move my range extender closer to the b-hive for it to connect. Even though the b-hive could see the home network. The home network was displaying only 2 bars on the b-hive but it still wouldn’t connect consistently until I got it a stronger 2.4ghz signal. It can’t connect to 5ghz.
I also had some luck after unplugging it after multiple attempts to connect and then plugging it back in.
Hope that helps.
