Can't resetup my ring doorbell

I have tried to reconnect my ring doorbell several times without success. I follow the procedures outlined in your setup instructions several times. Each time during the setup procedure the process stops with the white revolving circle stopping stops with the white arc on the left side of the circle. I have tried several times and the results are the same. The process stops with the white arc on the left side of the circle. The process will not go any further. What should I do?
