Random connection errors

[virtual-designer]

Which package is this bug report for?

discord.js

Issue description

Random connection errors especially when using slash commands. I'm 100% sure my connection is strong enough. The error is given below:

ConnectTimeoutError: Connect Timeout Error
    at onConnectTimeout (D:\Rakin\Projects\sudobot-v2\node_modules\undici\lib\core\connect.js:131:24)
    at D:\Rakin\Projects\sudobot-v2\node_modules\undici\lib\core\connect.js:78:46
    at Immediate._onImmediate (D:\Rakin\Projects\sudobot-v2\node_modules\undici\lib\core\connect.js:117:33)
    at processImmediate (node:internal/timers:464:21) {
  code: 'UND_ERR_CONNECT_TIMEOUT'
}

Code sample

// client = discord client
// this code might not always fail - for me the error was coming randomly

client.on('interactionCreate', async (interaction) => {
   if (interaction.isChatInputCommand()) {
      // do some stuff like bulk deleting messages or warning users

     await interaction.reply({ content: 'Done' });
   }
});

I found two instances of requests from djs that uses fetch as it'srequest source:

discord.js/packages/discord.js/src/util/Util.js

Line 227 in 5d8bd03

const response = await fetch(RouteBases.api + Routes.gatewayBot(), {

discord.js/packages/discord.js/src/util/DataResolver.js

Line 125 in 5b053cf

const res = await fetch(resource);

My bet would be in the first one, since it's called on every bot start!!
