Ethereum: My ubuntu server can’t connect to binance websockets with nodejs (errno: -111 | code: 1006 ECONNREFUSED)
Ethereum webSockets problems with noda.js on ubuntu server
As a developer that builds blockchain projects, connecting to Binance WebSockets using noda.JS can be crucial for exchanging and updating of real -time data. However, when you face questions like Errno: -111 | Code: 1006 ECONNREFUSED, it is crucial to resolve the connection process.
Understanding the error code
– Errno: -111 indicates an error that occurred during a system call.
– Code: 1006 ECONNREFUSED 'Declans that the connection was rejected by the server.
Ethereum webSockets steps for noda.js on Ubuntu server
Step 1: Install and Set Binance WebSockets
Before you try to connect, ensure you install Binance WebSockets:
Bash
SUDO APT update
SUDO APT Install Binance-Websocket-Klijent
`
Then set a relationship with your Ethereum account:
Bash
Echo “Username = Your_ethereum_userername” | Sudo Sed -i “/^WebSocket_userername/s/^\ (.*\)/\ 1″/etc/bashrc
`
Replaceyour_ethereum_userernamewith a user name Binance WebSockets.
Step 2: Set the Noda.JS environment
Make sure NODE.JS and NPM have been installed:
Bash
SUDO APT update
SUDO APT INSTALLS NODEJS NPM
`
Check the noda.JS version by launchingnoda -v.
Step 3: Create a simple websocket connection in noda.js
Create a new file calledServer.js(or any other name) with the following code:
Javascript
Const WebSocket = demand (‘WS’);
Const WSS = New WebSocket.server ({Port: 8080});
wss.on (‘link’, (ws) => {
Console.log (“client connected”);
// process the incoming data from clients
ws.on (‘message’, (message) => {
Console.log (received a message from the client: $ {Message});
// broadcast a received message to all clients
WSS.CLIENTS.FOOCH ((client) => {
if (client! == ws && client.Readystate === WEBSOCKET.OPEN) {
client.send (message);
Iche
});
});
// handling interruption of connection
ws.on (‘Close’, () => {{{{{{{{{{
Console.log (“client switched off”);
});
});
Console.log (“Server operating on Porto 8080”);
`
Step 4: Start NODE.JS server
Start the server by launching:
Bash
Node server.js
`
Open the new terminal window and connect to WebSockets Binance WebSockets with the WebSocket Client in Node.JS using the following code clip (ReplaceYouThereum_userernamewith the actual user name Binance WebSockets):
Javascript
Const WebSocket = demand (‘WS’);
Const WSS = New WebSocket.server ({Port: 8080});
wss.on (‘link’, (ws) => {
Console.log (“client connected”);
// process the incoming data from clients
ws.on (‘message’, (message) => {
Console.log (received a message from the client: $ {Message});
// broadcast a received message to all clients
WSS.CLIENTS.FOOCH ((client) => {
if (client! == ws && client.Readystate === WEBSOCKET.OPEN) {
client.send (message);
Iche
});
});
// handling interruption of connection
ws.on (‘Close’, () => {{{{{{{{{{
Console.log (“client switched off”);
});
});
Console.log (“WebSocket connection successfully established”);
``
Step 5: Resolution of Problem
If you still have problems, ensure that:
– Binance WebSockets username is correct.
– Your Ethereum account has enough Salda for gas fees to pay for the webSocket connection.
– Ubuntu server has enough resources (CPU, memory and belt width) to process the websocket connection.
Conclusion
Solving problems with connection problems on the websocket in the NODA environment.JS can be complex.
