The Console tab allows you to view live server logs and send commands directly to your Minecraft server.

This is one of the most powerful tools available for managing and troubleshooting your server.

Console & Logs

The main window displays real-time output from your server.

This includes:<br>- Player activity (joins, leaves, kicks)<br>- Errors and warnings<br>- Plugin/mod messages<br>- Server startup and shutdown logs<br>- Command results

Logs update continuously while the server is running.

Understanding Logs

Logs may look technical, but they provide useful information.

Example Messages

Player Connection Issues

Failed to verify username

Common causes:<br>- Player using cracked launcher<br>- Mojang authentication issue<br>- Server in online mode

Invalid Session

Username 'pizza' tried to join with an invalid session

Usually means:<br>- Player is not properly logged into Minecraft<br>- Session expired<br>- Authentication failed

Internal Exception

Internal Exception: java.lang...

Possible causes:<br>- Mod/plugin mismatch<br>- Version mismatch<br>- Network issues<br>- Corrupt data

Warnings

[WARN] handleDisconnection() called twice

Warnings are usually not critical but may indicate instability or bugs.

Follow Logs

Follow logs checkbox:

• Enabled: Console auto-scrolls as new logs appear
• Disabled: Console stays in place so you can read older entries

Recommended:<br>Leave enabled during normal use.

Disable when reviewing errors.

Refresh Now

Manually refreshes the console output.

Use this if:<br>- Logs appear stuck<br>- You disabled "Follow logs"<br>- You want to reload recent output

Sending Commands

Use the input box at the bottom to send commands directly to your server.

Example input:

op Steve

Click Send or press enter to execute the command.

Common Commands

Operator (Admin)

Grant admin privileges:

op <player>

Remove admin:

deop <player>

Player Management

Kick a player:

kick <player>

Ban a player:

ban <player>

Whitelist a player:

whitelist add <player>

Server Control

Stop the server:

stop

Save the world:

save-all

Game Settings

Change gamemode:

gamemode creative <player>

Change time:

time set day

Important Notes

- Commands do not use / in the console<br>Example: use op Steve, not /op Steve

• Commands execute immediately
• Some in-game commands require operator (admin) permissions

Troubleshooting

Server not responding to commands

Check:<br>- Server is running<br>- No crash occurred (look for errors in logs)

Players cannot join

Look for:<br>- "Failed to verify username"<br>- Version mismatch errors<br>- Mod mismatch errors

Server crashing

Search logs for:<br>- ERROR<br>- Exception<br>- Crash

These usually appear just before the crash.

Mods/plugins not working

Check for:<br>- Missing dependencies<br>- Version mismatches<br>- Load errors during startup

Tips

• Use the console instead of in-game chat for admin commands
• Copy errors from logs when troubleshooting
• Use logs to identify exactly when issues started
• Keep "Follow logs" enabled during normal operation
