Discord Bot Token Invalid - Troubleshooting & Fix

Problem

The Discord bot is failing to login with error:

❌ Unhandled Promise Rejection: Error [TokenInvalid]: An invalid token was provided.

This means the DISCORD_BOT_TOKEN environment variable is either:

• Expired or revoked

• Invalid/malformed

• For a bot that was deleted from Discord Developer Portal

• Not properly synced to the deployment environment

Solution: Get a New Bot Token

Step 1: Go to Discord Developer Portal

1. Visit: https://discord.com/developers/applications

2. Sign in with your Discord account

3. Click on the application named "AeThex" (or your app name)

Step 2: Get the Bot Token

1. Click on the "Bot" tab on the left sidebar

2. Under the "TOKEN" section, click "Reset Token"

3. Click "Yes, do it!" to confirm (the old token will be revoked)

4. Click "Copy" to copy the new token

Step 3: Update the Environment Variable

The new token looks like: NTc4OTcxMjQ1NDU0OTUwNDIx.GxxxXX.xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

For Railway/Spaceship Deployment:

1. Go to your Railway/Spaceship dashboard

2. Go to environment variables

3. Update or add: DISCORD_BOT_TOKEN=<new_token_here>

4. Save changes

5. Redeploy the bot

For Local Development:

1. Update .env file in code/discord-bot/:

   DISCORD_BOT_TOKEN=your_new_token_here

2. Restart the bot: npm start

Step 4: Verify the Bot

After updating the token, the bot should:

1. Login successfully: ✅ Bot logged in as AeThex#xxxx

2. Load all commands: ��� Loaded command: verify, etc.

3. Start health check server: 🏥 Health check server running on port 8044

Token Format Validation

A valid Discord bot token:

• ✅ Starts with a number (user ID)

• ✅ Contains 3 parts separated by dots: part1.part2.part3

• ✅ Is ~70+ characters long

• ✅ Contains only alphanumeric characters, dots, hyphens, and underscores

Example: NTc4OTcxMjQ1NDU0OTUwNDIx.GxxxXX.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Common Issues & Fixes

Issue: "Token has been exposed"

Discord automatically revokes tokens if they appear in public repositories (GitHub, etc.).

Fix: Reset the token in Discord Developer Portal as described above.

Issue: Bot not in any servers

Even with a valid token, the bot might not connect to your servers.

Fix:

1. In Discord Developer Portal, go to OAuth2 > URL Generator

2. Select scopes: bot

3. Select permissions: Administrator (or specific permissions)

4. Copy the generated URL and open it in browser

5. Select your server and authorize

Issue: "TokenInvalid" but token looks correct

The token might be:

• Copied with extra whitespace

• Not fully copied (missing characters)

• From a different bot application

Fix:

1. Go back to Discord Developer Portal

2. Reset the token again (this revokes the old one)

3. Copy the full new token carefully (no extra spaces)

4. Update environment variable immediately

Environment Variables Checklist

Before deploying, verify these are set:

• ✅ DISCORD_BOT_TOKEN - Valid bot token from Developer Portal

• ✅ DISCORD_CLIENT_ID - Usually 578971245454950421

• ✅ DISCORD_PUBLIC_KEY - From General Information tab

• ✅ SUPABASE_URL - Database connection

• ✅ SUPABASE_SERVICE_ROLE - Database authentication

• ✅ BOT_PORT - Usually 3000 or 8044 for Railway

Still Having Issues?

If the token is valid but bot still won't login:

1. Check Discord Server Status: https://status.discord.com/

2. Verify Bot Permissions: Make sure bot has "Send Messages", "Read Messages"

3. Check Firewall: Some firewalls block Discord API connections

4. Review Recent Changes: Did you recently update discord.js version?

5. Clear Cache: Delete node_modules/ and run npm install again
