Relay Node unable to connect to Producer node

Staking & Delegation Operate a Stake Pool
1

Hi all I have just installed 2 x Ubuntu 20.04 LTS servers. I have configured them both and am running them in a local network.

My relay node is working great however it can’t connect to my producer node. However my producer node can connect to my relay.

This is not a networking issue as they are in the same subnet and software firewall is off, this is for sure a configuration issue. I have tried changing the port and also running with:

cardano-node run --topology ~/mainnet-topology.json --database-path db/ --socket-path node.socket --host-addr 0.0.0.0 --port 3032 --config ~/mainnet-config.json

Troubleshooting:

On my producer node port is listening:

tcp LISTEN 0 8 0.0.0.0:3032 0.0.0.0:*

And is connected to the relay:

tcp ESTAB 0 0 10.xxx.0.3:46515 10.xxx.0.2:3000

However the relay won’t connect with the error:

[CryptoRo:cardano.node.IpSubscription:Notice:303] [2021-02-25 07:57:57.47 UTC] IPs: 0.0.0.0:0 [10.xxx.0.3:3032] Connection Attempt End, destination 10.xxx.0.3:3032 outcome: ConnectSuccessLast

[CryptoRo:cardano.node.IpSubscription:Error:82] [2021-02-25 07:57:57.50 UTC] IPs: 0.0.0.0:0 [10.xxx.0.3:3032] Failed to start all required subscriptions

I am running 10.25.1, does anyone have any ideas? Do i need to reinstall my producer node?

I have checked the node.socket and its path varialbe which are good also on both side.

Is there a way for debug logging in cardano-node?

can you try from your relay

telnet PRODUCER_IP 3002

what is the output?

Telnet is working:

~# telnet 10..0.3 3032
Trying 10..0.3…
Connected to 10.***.0.3.
Escape character is ‘^]’.

4

ok. now check in your topology updater script, u wrote the right address?

Do you mean here:

root@Relay:~# cat mainnet-topology.json
{
“Producers”: [
{
“addr”: “relays-new.cardano-mainnet.iohk.io”,
“port”: 3001,
“valency”: 2
},
{
“addr”: “10.***.0.3”,
“port”: 3032,
“valency”: 2
}
]
}

The address is correct, I also found an occasional error in the producer log which looks like this:

[:cardano.node.ErrorPolicy:Warning:77] [2021-02-25 09:08:38.00 UTC] IP 10.131.0.2:39053 ErrorPolicySuspendPeer (Just (ApplicationExceptionTrace (MuxError (MuxIOException Network.Socket.recvBuf: resource vanished (Connection reset by peer)) “(recv errored)”))) 20s 20s

But that doesn’t happen very often only really when i restart the produce i think.

If I stop the producer node, the relay node shows this error:

[:cardano.node.ErrorPolicy:Notice:76] [2021-02-25 09:05:07.96 UTC] IP 10.***.0.3:3032 ErrorPolicySuspendConsumer (Just (ConnectionExceptionTrace Network.Socket.connect: <socket: 49>: does not exist (Connection refused))) 20s

So i am sure it is not a networking issue as it sees the port once its started, the producer is just refusing the connection for some reason.

the relay and Producer are synced? I know mines not connecting to Producer if them are not synced

7

Relay is synced but the producer is still syncing from the relay, could that be the issue?

8

Yes, this is the issue; wait till Producer will be synced

Okay no problem at all thanks for your help! Will update once synced
