You should have no issue with the DNS seednodes that are hardcoded, but here you go:

        "addr" : "45.32.178.232",
        "addr" : "108.61.216.195",
        "addr" : "54.37.46.84",
        "addr" : "71.213.38.4",
        "addr" : "82.70.129.110",
        "addr" : "208.38.200.241",
        "addr" : "90.196.80.78",
        "addr" : "185.220.100.247",
        "addr" : "191.177.203.233",

If peers are dropping you, you may want to verify your copy of the blockchain against an explorer. If you find you've forked, a recent snapshot is available via the sterlingcoin.org website (Download > Recent Snapshot).

Sorry it is giving you difficulties.

Happy Mother's Day any moms out there!
