This error indicates the pairing process has been canceled. Typically this is a user driven action however there is a possibility the user did not mean to select this option.
Please follow these instructions in order to resolve the issue:
1. Wait 2 minutes and then proceed to unpair once again. This may allow enough time for pending requests to complete.
2. If the issue persists - identify at what step in pairing did the action cancel and inform your support team.
