What is the proper way to use discord.js with proxy server?

I want to run my Discord bot using a different IP address for both HTTP (REST API) and WebSocket (WSS) connections — so that all outbound traffic from the bot is routed through a specific proxy. So far I have such simple configuration:

import "dotenv/config";
import { setGlobalDispatcher, ProxyAgent } from "undici";
import { Client, GatewayIntentBits } from "discord.js";

setGlobalDispatcher(new ProxyAgent(process.env.PROXY_URL!));

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
    GatewayIntentBits.MessageContent,
  ],
});

client.once("ready", () => {
  console.log(`Logged in as ${client.user?.tag}`);
});

client.login(process.env.DISCORD_TOKEN);

import "dotenv/config";
import { setGlobalDispatcher, ProxyAgent } from "undici";
import { Client, GatewayIntentBits } from "discord.js";

setGlobalDispatcher(new ProxyAgent(process.env.PROXY_URL!));

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
    GatewayIntentBits.MessageContent,
  ],
});

client.once("ready", () => {
  console.log(`Logged in as ${client.user?.tag}`);
});

client.login(process.env.DISCORD_TOKEN);

But it gives me timeout error (or doesn't output anything):

node version: v22.11.0 discord.js: ^14.18.0, My proxy has http(s) type. It is indeed working. I have successfully requested main discord page through my proxy with https.

Hi! I'm not very experienced yet, but I suspect the bot needs to use WebSocket to function fully. In that case - yes. I need to proxify webscoket connection as well.

As far as I know, if HTTPS is supported, then WSS should be supported as well (depends on proxy provider, but most of the times works that way). I even wrote a small code snippet to verify that WebSocket works correctly with my proxy:

import WebSocket from "ws";
import { HttpsProxyAgent } from "https-proxy-agent";
const agent = new HttpsProxyAgent("...");
const ws = new WebSocket("wss://gateway.discord.gg/?v=10&encoding=json", { agent });
ws.on("open", () => {
  console.log("Success.");
  ws.close();
});
ws.on("error", (err) => {
  console.error("Failed:", err.message);
});

import WebSocket from "ws";
import { HttpsProxyAgent } from "https-proxy-agent";
const agent = new HttpsProxyAgent("...");
const ws = new WebSocket("wss://gateway.discord.gg/?v=10&encoding=json", { agent });
ws.on("open", () => {
  console.log("Success.");
  ws.close();
});
ws.on("error", (err) => {
  console.error("Failed:", err.message);
});

Success was the result.

the WSS connection may not be routed correctly through the proxy using undici bec undici handles HTTP traffic not WebSockets i think, the handshake timeout error indicates that the websocket connection to discord is being blocked but also consider these: - timeouts - prooxy config => make sure that ur proxy supports websocket tunneling, most HTTPS proxies do but there could be cases where some configs / restrictions prevent websocket connections Correct me if I'm wrong

I use proxychains for this. just run the bot with this: proxychains4 -q -f /path/to/proxychains4/config.conf node index.js. all requests coming out of this process including websocket will automatically use the configured proxy server sample from one of my proxychain configurations:

strict_chain
proxy_dns
remote_dns_subnet 224
tcp_read_time_out 15000
tcp_connect_time_out 8000
[ProxyList]
http proxy_ip_here proxy_port_here

tcp_connect_time_out 8000
