The problem was that the SpaceX team couldn't provide sufficient confidence of a full load of TEA-TEB.

from live thread:
https://forum.nasaspaceflight.com/index.php?topic=32783.msg1123295#msg1123295QuoteWhat we know is that the TEA-TEB igniter line or lines became too cold, it is unknown if they "froze" or the fluids inside simply became too viscous to function properly.
