Error: connection not open on send() when trying to connect NodeJs to my Private Geth Node

Question

hope all are good ? I have a pb with my FULL NODE i can't connect it with my nodeJs files I can use my node if file's url is localhost:8546, i'm able to run my script from my server only but i want use my servr with my PC

From my server folder :

root@x:/home/x/bsc/build/bin

For Geth i run command :

./geth console --config ./config.toml --datadir ./node --cache 8000 --maxpeers 500000000 -- 
rpc.allow-unprotected-txs --txlookuplimit 0 --syncmode full --ws --ws.addr *0.0.0.0**
 ws.port 8546 --wsorigins '*'  --wsapi web3,shh,txpool,debug 

Geth is synced

My server have port open for : ssh 22 / port 8546 tcp and udp

I can connect with PUTTY

My files is:

const Web3 = require('web3');
const wsProvider = new Web3.providers.WebsocketProvider("ws://MyiPNodeAddress:8546")
const web3 = new Web3(wsProvider);


web3.eth.getBlockNumber().then((result) => {
  console.log("Latest Ethereum Block is ",result);
});

and return this :

Error: connection not open on send()

I'm using my mobile phone network connected to my Windows and i'm trying to connect to my geth linux server node then. I can't connect with my node can someone explain me please why ?

Sincerely Mike

Answer 1

I am not sure if it will make difference, but make some slight adjusts in the Geth call command:

./geth console --config ./config.toml --datadir ./node --cache 8000 --maxpeers 500000000 --rpc.allow-unprotected-txs --txlookuplimit 0 --syncmode full --ws --ws.addr **0.0.0.0** --ws.port 8546 --ws.origins '*'  --ws.api web3,shh,txpool,debug

Also, you can install geth in your Windows, if you want, and try to connect with your server to test if it is open to connections:

geth attach ws://MyiPNodeAddress:8546

Finally ws is not secure, consider to connect to your server through ssh tunnel with the command and alteration in code:

ssh -N -L 8546:localhost:8546 <user>@MyiPNodeAddress

const wsProvider = new Web3.providers.WebsocketProvider("ws://localhost:8546")

Answer 2

I think i made a mistake if i run script in my server all work good, but i want run script from my .js files from my Visual Studio Code and actually if do

const wsProvider = new Web3.providers.WebsocketProvider("ws://MyiPNodeAddress:8546")

it didn't work but if i run my .js directly from my server the scripts have :

const wsProvider = new Web3.providers.WebsocketProvider("ws://localhost:8546")

and it always work

I want run my script with my windows not my server i know this is better to run it with my server but its only to collecting some information not to run finnaly without ssh tunel, i just want to put my ip and work ...
