Solution 3 worked for me!

Solution 4:

Unpair your device and then pair it again. Thereafter follow Step 3.

I clicked ‘Cancel Running’, opened the Devices list, unpaired my iPhone, removed my USB cable and reconnected it, paired the iPhone, and then was asked on my iPhone to enter my passcode (pin code). Did this and then was finally able to pair my phone correctly.
