DnsSubscription warning

Staking & Delegation Setup a Stake Pool
,
#1

Hi, this is my first time posting here. I’ve been looking for a solution to my error on this forum with no luck so I am hoping someone can help me directly.

I followed CoinCashews guide to setup 3 Cardano nodes and am now trying to register my stake address. I am not able to see my TxHash TxIx or amount of ada in my payment address when using

cardano-cli query utxo --address $(cat payment.addr) --mary-era --mainnet

I then used journalctl --unit=cardano-node --follow to see if the blockchain has synced successfully (which it has prior to starting the node as a blockproducing node) and noticed this error:

[relay1-V:cardano.node.DnsSubscription:Warning:95] [2021-03-27 07:46:14.55 UTC] Domain: “<169.239.9.26>” Failed to start all required subscriptions
on my relay node
and this error
[relay1-V:cardano.node.DnsSubscription:Warning:95] [2021-03-27 07:46:14.55 UTC] Domain: “<169.239.9.27>” Failed to start all required subscriptions
on my BP node.

Any help would be appreciated. Please ask for the required files to resolve the error as I am unsure what to include.

What I’ve tried: Failed to start all required subscriptions error - #3 by mdsullivan

using -znv <other_nodeIP> <other_node_port> to see if the nodes connect which they do
successfully

and sudo netstat -lnaopt resulting in :

Hi!

Please provide content of both topology files to see what ports you add in it.

#4

Hey, @laplasz thanks for the swift reply!

Relay node:
{

"Producers": [

  {

    "addr": "169.239.9.26",

    "port": 6000,

    "valency": 1

  },

  {

    "addr": "relays-new.cardano-mainnet.iohk.io",

    "port": 3001,

    "valency": 2

  }

]

}

Producer node:
{

"Producers": [

  {

    "addr": "169.239.9.27",

    "port": 6000,

    "valency": 1

  },

]

}
Thanks

#5

so netstat clearly shows that IP of the relay node is 169.239.9.26 since this IP is used which connect to IOHK server:

tcp 0 0 169.239.9.26:34651 18.158.188.21:3001 ESTABLISHED 1294499/cardano-nod off (0.00/0/0)

that means the IPs in the topology files should be replaced by eachother.
so relay topology should contain BPs IP: 169.239.9.27, and BP topology should contain IP of relay: 169.239.9.26

Hope this helps!
(probably when you tried to netcat it just connected to itself, and not to the other)

#6

so I tried swapping the IP and the error still persists, I double-checked the IP for both the producer and the relay.
BP is definitely set to 169.239.9.26 and relay to 169.239.9.27…

I’m guessing I somehow made a mistake when configuring the BP?

#8

so maybe the use of topology files are mixed up - so block producer started with relay node topology…
what is the status of the service to see which topology was used when starting the node

#9

can you please edit your previous post with adding the netstat info about your producer node as well?

Im assuming I should post the output of this command on the relay?

#11

So as you can see that both nodes connects to IOHK server:
relay:

bp:

tcp 0 0 169.239.9.26:34651 18.158.188.21:3001 ESTABLISHED 1294499/cardano-nod off (0.00/0/0)

which is suspicious… that means BP using the relays topology file…
give status of both

relay: /home/relay1/cardano-my-node/mainnet-topology.json
bp: /home/chris/cardano-my-node/mainnet-topology.json

so these nodes are on the same machine with different virtual interfaces?

#14

They are running on 2 different servers, I have another relay node setup on the same server as relay 1 but I’ve haven’t connected it to the bp as of yet since I’m trying to get relay 1 to work. The bp is on a dedicated Linux Ubuntu server

#15

can you just start bp, so kill the relay…
and then see what netstat gives back for bp - there should not be any ESTABLISHED connection

#16

also when you start the node - you can find the remote addresses where the node will attempt to connect at the beginning of the node logs… can you please share the logs content?

#17

I killed both relays this is the result on the BP
Its clearly still connected…

I dont see any connect info in the logs when using journalctl --unit=cardano-node --follow

the node generates logs which can be found under logs/ in the node folder… do you have such?
also list all the processes which is running:
ps -ef | grep cardano

I’m not sure, may be 169.239.9.27 is not public ip. it is under your proxy.
