Peer getting rejected from the private network

Question

Hi I created a private network of 3 nodes with the following configurations like this:

# more than one node should validate. threashold = 2
[QUORUM_SET]
THRESHOLD_PERCENT=34
VALIDATORS=["$node01","$node02","$node03"] 

so {node01, node02, node03} forms a quorum.

Now I want to connect another node - node04 with the following configuration :

[QUORUM_SET]
THRESHOLD_PERCENT=1
VALIDATORS=[
]
# threshold  = 3 (more than 2 nodes should validate)
[QUORUM_SET.1]
THRESHOLD_PERCENT=51
VALIDATORS=[
    "$node01", 
    "$node02", 
    "$node03",
    "$self"
]

But the node04 is getting reject and getting outofsync and hence not getting consensus. here is the error at node04 console :

2019-06-13T14:26:15.995 GD6ED [Overlay WARNING] Received error (ERR_LOAD): peer rejected

Error at one of the other nodes :

New connected peer (empty)

2019-06-13T15:03:52.813 GCOQO [Overlay INFO] Dropping peer [email protected]:11655

Here I have 2 questions:

• Q1) Am I doing some incorrect configuration ?
• Q2) When I am adding node04, then, in that case, the quourum is still {node01, node02, node03} right?
• Q3) Is there any proper documentation of connecting a new node with main network ?

TIA!

Edit:

I stopped all of the nodes and added node04 in the list of preferred peers and restarted everything again and it worked.

Now the question is, In case I want to become a validator node in main network , then do I have to publish my IP to the community so that they can add me in their preferred peers?

Answer 1

You don't have to publish your IP. Once you're connected to the network your address will be somehow announced and you'll get incoming connections pretty soon.

Answer 2

I understood what I was doing wrong. I had set PREFERRED_PEERS_ONLY=true which is why it rejected other incoming peers. After setting it to false the network working fine.

So if you get stuck with this kind of situation check the following thing in your network configurations:

1. Check for TARGET_PEER_CONNECTIONS
2. Check for MAX_ADDITIONAL_PEER_CONNECTIONS
3. Check for PREFERRED_PEERS_ONLY
