After updating, I can no longer connect the Apple Watch to the iPhone.

After a software update i am not able to connect my wife’s apple watch to her phone. The phone says Bluetooth is connected but the watch never stops trying to connect. It was connected but after updating i can no longer connect the watch to the phone. When I do the pairing the phone says it is connected but the watch never get past connecting, not paired
