This error indicates that the user canceled the pairing process when asked to confirm their authorization with their current password.
Please follow these instructions in order to resolve the issue:
1. Wait 2 minutes and then proceed to pair once again. This may allow enough time for pending requests to complete. During the step where a prompt appears, do not dismiss it. Enter your credential to complete pairing.
