Include a reproducible code sample here, if possible:
Well there are 2 kinds of functions I use:

app.post("/sendHappyHourEndMessage/", function (req, res) {
    let message = req.body.message

    const embed = new Discord.RichEmbed()
        // Set the title of the field
        .setTitle(`Termino el Happy Hour!!`)
        .setImage('https://raw.githubusercontent.com/ao-libre/ao-api-server/master/resources/images/happy-hour-end-discord.png')
        .setFooter(website, iconFooter)
        // Set the color of the embed
        .setColor(0x641b06)
        // Set the main content of the embed
        .setDescription(message);

    const channel = global.clientDiscord.channels.find(x => x.name === "general")
    channel.send(embed)
    return res.status(200).json(embed);
});

And

clientDiscord.on('message', message => {
    if (message.content === 'ping') {
        message.reply('pong');
    }

    if (message.content === '/online') {
        const usersOnline = getOnlineUsersQuantityInServer()
        message.reply(`En este momento hay: ${usersOnline} conectados en el servidor de Rol Alkon 0.13.X`);
    }
});

Further details:

• discord.js version: "^11.5.1",
• Node.js version: v10.16.0

I think this is related, but as they said in the docs there is no info for error handling

[monbrey]

As per #2523 which you seem to have read, you need to attach a listener to the Client#error event.

This particular error is ETIMEDOUT which is just a connection issue with Discord. Not a bug.

If you need help with discord.js installation or usage, please go to the discord.js Discord server instead:

This issue tracker is only for bug reports and enhancement suggestions.

Yes we can close this as here https://github.com/discordjs/discord.js/issues/2879 everything is clear

although i recommend put something in the documentation to avoid more issues related with this, so everyone knows how to handle this easily :)
