Debian jessie gets the start dependencies wrong and starts gpsd before starting chronyd.
The simple fix is to stop gpsd, wait a few seconds and then restart it. It should then attach to the chrony listening socket.
A long term fix is to sort out the dependencies. There was a lot of discussion of this on the gpsd mail list a few months back. A search of the their archives may be helpful.
