[2019-02-01 01:00:18,225 WARNING zil.py:55] unauthorized public key: 0x031d55508205360983a02f5e785a86e00d5d52b990c932467e5c68a9b4fcd49cfd

But the pubkey is valid and used to join the network successful
xxx+ 5710 1 10 07:54 pts/1 00:00:10 /home/xxx/Zilliqa/build/bin/zilliqa --privk xxx --pubk 031D55508205360983A02F5E785A86E00D5D52B990C932467E5C68A9B4FCD49CFD --address xxx --port xxx --synctype 1

I found the zil.py that line 55 is calling zilnode.py function ZilNode and call

def get_by_pub_key(cls, pub_key, authorized=True):
query = mg.Q(pub_key=pub_key)
if authorized is not None:
query = query & mg.Q(authorized=authorized)
return cls.objects(query).first()

is it need to add anything to mongo db to make this pubkey authorized?

You need to register your node's pubkey first, and then the admin's email will receive a link to approve it.
