Block Producing node having issue connecting to relay node

Staking & Delegation Setup a Stake Pool
1

Hello,

I am new to Cardano, love everything about it so far! I am trying to start a staking pool. I been following this guide so far.

I set up two VMs in digital ocean. Relay node seems to run fine. However my BP node and relay node are having issue on start.

My BP keeps error/restart when I attempt to start the node.

(67.205.167.232) is my relay node’s public IP

[cardano:cardano.node.IpSubscription:Error:122] [2021-05-26 04:03:28.05 UTC] IPs: 0.0.0.0:0 [67.205.167.232:6000] Connection Attempt Exception, destination 67.205.167.232:6000 exception: Network.Socket.connect: <socket: 60>: does not exist (Connection refused)

This is my mainnet-topology.json

root@cardano:~/cardano-my-node# cat mainnet-topology.json 
 {
    "Producers": [
      {
        "addr": "67.205.167.232",
        "port": 6000,
        "valency": 1
      }
    ]
  }

Here is some info helpful for debugging

deleting db folder and restart seem to do the trick

On relay u will need to open the port 6000 for any not only for ur producer… otherwise other nodes can’t connect to the relay and u will not see TX processed

gotcha, thanks for the tip! Updated
