Python Discord bot unexpectedly stops responding

I’m having trouble with my Discord bot running on a friend’s Raspberry Pi VPS. It starts fine and responds to commands for about 5 minutes. Then it stops working properly. When I click the green button, Discord shows “Interaction Failed”. If I send the command again, it works and keeps the user ID in the sign-in dictionary. But after another 5 minutes, the same issue happens.

The bot isn’t completely stopping, but something’s not right. Could this be a code issue or a VPS problem? Here’s a simplified version of my code:

import discord
from discord.ext import commands

bot = commands.Bot(command_prefix='!', intents=discord.Intents.default())

registrations = {}

@bot.command()
async def signup(ctx):
    button = discord.ui.Button(label='Register', style=discord.ButtonStyle.green)
    
    async def button_click(interaction):
        if interaction.user.id in registrations:
            await interaction.response.send_message('Already registered', ephemeral=True)
            return
        
        await interaction.response.send_modal(RegistrationForm())

    button.callback = button_click
    view = discord.ui.View()
    view.add_item(button)
    await ctx.send('Click to register', view=view)

class RegistrationForm(discord.ui.Modal):
    def __init__(self):
        super().__init__(title='Registration Form')
        self.name = discord.ui.TextInput(label='Name')
        self.add_item(self.name)

    async def on_submit(self, interaction):
        registrations[interaction.user.id] = {'name': self.name.value}
        await interaction.response.send_message('Registration complete!', ephemeral=True)

bot.run('YOUR_TOKEN_HERE')

Any ideas on what might be causing this intermittent issue?

I’ve encountered similar issues with Discord bots before. In my experience, it is often due to rate limiting or connection instabilities rather than a mistake in the code. Implementing solid error handling and logging allowed me to identify where the bot was losing connection. I also used background tasks to keep the bot active, which prevented inactivity timeouts. Additionally, I found that monitoring the VPS network stability and having a watchdog script to restart the bot when unresponsive really helped stabilize the service.

sounds like ur bot might be timing out due to inactivity. try adding a heartbeat to keep the connection alive. also, check the vps’s resource usage - maybe its running low on memory or cpu. could be worth implementing some error logging to catch any exceptions that might be causing this. good luck troubleshooting!

This issue could be related to the bot’s connection to Discord’s gateway. The intermittent nature suggests a potential disconnection problem. I’d recommend implementing a reconnection mechanism using the on_disconnect and on_ready events. Also, consider adding error handling for potential exceptions in your command functions.

To diagnose further, implement logging throughout your code, especially in the signup function and RegistrationForm class. This will help pinpoint where the bot might be failing. Additionally, monitor the VPS’s network stability and resource usage during these occurrences.

If the problem persists, you might want to look into using a process manager like PM2 to automatically restart the bot if it crashes or becomes unresponsive. This could serve as a temporary workaround while you investigate the root cause.
