Your house has water, but the outside water faucet has none.
This problem can simply a build up of sediment on the valve stem, which can happen to inside faucets, as well.
To determine if the problem is the result of sediment build up, remove the stem from the faucet and turning on the water.
Water should come out of the spigot. If it doesn’t, try cleaning out the stem area to remove any debris.
If, after removing the debris, you still don’t have any water flowing, a plumber should be contacted who will determine the problem and correct it.
