Auto voice mail password sign in

Set this up two weeks ago and it worked perfectly on my Verizon S5. Did *86,xxxx#. Yesterday it stopped working altogether saying the number was not valid. The password worked perfectly manually. I tried two ,, and nothing. I tried three ,,, and it worked again for two times then back to the number is not valid.
Does anyone know why this would happen?
Thanks.

Works on mine but I don't have the # on the end, just pause (,) and 4 digit pin.
