Network.socket.connection NFT cardano-cli install

[Diego_Fernando_Escob]

Hello everybody. I started to install all the Cardano Environment because I wat to mint NFTs, so I have not created a pool or stake pool. I already have cardano-cli installed version 1.27.0 and all the steps from Cardano docs. From Mainnet , I need the tip, slot/block. When I try to do

cardano-cli query tip --mainnet

it responds

cardano-cli: Network.Socket.connect: <socket: 11>: does not exist (No such file or directory)

I saw in different forums that it can be because I dont have a node running. So I run my node and I see how I get “Chain Extended:…” and I get block and slot number increasing… Until I get this error -image attached-.

Then, based on that error, I read that it was because I dont have my cardano block running. So I run it, but it keeps telling me that I dont have my node.cert.

And when I see how to create my node.cert, I found that it depends to generate it AGAIN the data I should receive from “cardano-cli query tip --mainnet” to calculate it.

What can I do to solve that error and retrieve the data I need?
So what can I do about it? Thank you in advance!!

Did u used coin cashew guide right?

U will need to download the files again

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-byron-genesis.json

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-shelley-genesis.json

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json

restart the node

[Diego_Fernando_Escob]

Alex Thank you very much, indeed im using that guide the cardano documentation, and im using these youtube video
As you can see he just type:
cardano-cli query tip --mainnet
and get all the information, but Im not sure if it is necessary to create a pool in order to create the NFTs

How to mint an NFT on the Cardano blockchain

I already have those files in : cardano-node/configuration/cardano

Don I need to put them in another place? To restart the node is killing the cardano process an then open it again with the comand cardano-node run?

I follow this forum as well Cardano-cli: Network.Socket.connect: <socket: 11>: does not exist (No such file or directory) - #7 by Tuan_Lam
And Im pretty sure I have the PATHs already well defined.

Is there another possible thing to do? Thank you again @Alexd1985

[Alexd1985]

U have an issue with the epoch/era transition (if u look at ur picture)
And it’s related with

Node not syncing after epoch 207 (14.9%) Please help

For what its worth I had no issues till 1.27… so dont spend to much time rebuilding machines (I’ve already spent it for you )

PS: the node should be synced with the blockchain in order to create NFTs

[Diego_Fernando_Escob]

Hi @Alexd1985 I tried to replace the files but is still not working.

Im new in cardano dev, BTW now that you mencioned the coincashew guide…

Do I need two servers? One for the relay node and another one for the producer node?

Or this is only for the stake pools? o for NFTs is only one server?

Thanks a lot Alex

[Alexd1985]

Producer and relays are only for pools; if u will want only a cardano node, then it’s enough a single node

What error do u see now?

[Diego_Fernando_Escob]

I`ve tried all day (and night) to replace the files you suggest, but i still get this error

Im thinking in get a new VPS and restart all the proccess, wich tutorial do you recomend to me?
The coin cashew guide Guide: How to build a Cardano Stake Pool - CoinCashew
For the node creation should I follow until which point in the guide?
@Alexd1985 Thank you again for your great community support

[Alexd1985]

Nope, wait still same error?

[Diego_Fernando_Escob]

@Alexd1985 TY !! Yes, I’ve seen how you suggest different users to use this hash “1a3be38bcbb7911969283716ad7aa550250226b76a61fc51cc9a9a35d9276d81”

I did it. But when I run :

cardano-node run
–topology ~/src/cardano-node/configuration/cardano/mainnet-topology.json
–database-path ~/cnode/db
–socket-path ~/cnode/db/node.socket \
–host-addr myhostaddress
–port 3001
–config ~/src/mainnet-config.json

When I run this command with your suggested hash, the console ask me for the previous genesis hash “67f10d861ce22c2afcdc48cb20dc1014e7b2ca97319ac945326ccf3425a5a2e7”.
For me only works it is the one I can find here
https://docs.cardano.org/projects/cardano-node/en/latest/stake-pool-operations/getConfigFiles_AND_Connect.html

I do have all the programs and versions up to date for cardano-cli 1.27.0. The thing is that followed different tutorials and I know that I have several copies of different directories and repos so finally I dont get what files to erase or clean.
Any idea?

[Alexd1985]

Ok, go to the folders where u have the files and

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-byron-genesis.json
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-shelley-genesis.json

Restar the node and check again

[Diego_Fernando_Escob]

@Alexd1985

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json

Ok I will do it. I was reading so I decided to use

cardano-node run --validate-db

In this moment is sync (I think until epoch 207). Do I need to wait this process to finish before do any change?

[Alexd1985]

Yes, let me know when the issue ocurre

[Diego_Fernando_Escob]

Ok it finished to sync and started to show again this error. But I can say that this time it got “further” and sync more slots before it stopped working. This is my very first installation btw.

and when I run
cardano-node run
–topology ~/src/cardano-node/configuration/cardano/mainnet-topology.json
–database-path ~/cnode/db
–socket-path ~/cnode/db/node.socket
–host-addr myhostaddress
–port 3001
–config ~/src/mainnet-config.json

I did change the files as you suggested and I get this message

[Alexd1985]

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json

Restart the node

nano mainnet-config.json and show me the ShelleyGenesisHash

[Diego_Fernando_Escob]

@Alexd1985

wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json

Exactly, I have the screenshots:

I got the paths, the hash, the file from the link, but it continues saying that the actual hash is different from the updated file as shown in the image

[Alexd1985]

try this one, perhaps they fixed

wget https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/mainnet-shelley-genesis.json

[Diego_Fernando_Escob]

@Alexd1985

wget https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/mainnet-shelley-genesis.json

It changes the error message as seen the whole process in the image below

InvalidYaml (Just (YamlException “Yaml file not found: /root/src/mainnet-config.json”))

cardano-node: YAML exception:
Yaml file not found:

[Alexd1985]

but I see differents path for files in your script

for example topology file and configuration files have different path; aren’t them located in the same folder?

also start the script with host-addr 0.0.0.0

[Diego_Fernando_Escob]

No they aren’t for some reason:

When I use the config file from the dir where the topology and genesis files are, it get me an error.

When I use the path of the config file from my $HOME it works!

I will try put them all in the same directory and let you know. They must be together?

[Alexd1985]

no, but check the path from script (if the files are located there)
