If you play Roblox for long periods without touching your keyboard or mouse, you've probably seen Error Code 278, which says you were "disconnected for being idle 20 minutes." This is Roblox's built-in system to free up servers when players go AFK (Away From Keyboard).
The good news? You can prevent Error 278 by staying "active" automatically. Below is a simple, beginner-friendly guide on how to fix Error 278 by AFKing in Roblox using an auto clicker.
What Is Roblox Error 278?
Roblox Error 278 appears when:
- You don't move, click, or press any keys for 20 minutes
- Roblox assumes you're inactive
- The server disconnects you automatically
This happens often when:
- Grinding in simulators
- Waiting in tycoon games
- AFKing for rewards, coins, or drops
- Leaving Roblox open while doing something else
Why an Auto Clicker Fixes Error 278
Roblox only checks if input is happening, not whether you're actually playing.
An auto clicker:
- Clicks your mouse automatically
- Keeps your character "active"
- Prevents the 20-minute idle timer
- Lets you AFK safely without disconnecting
How to AFK in Roblox Using an Auto Clicker (Step-by-Step)
Step 1: Download a Trusted Auto Clicker
Use a simple and well-known auto clicker, such as:
- OP Auto Clicker
- Free Auto Clicker
- GS Auto Clicker
Always download from the official website to avoid malware.
Step 2: Open Roblox and Join Your Game
- Launch Roblox
- Join the game you want to AFK in
- Make sure your character is fully loaded
Step 3: Set Up the Auto Clicker
Recommended settings:
- Click type: Left click
- Click interval: 5–10 seconds
- Repeat: Until stopped
A slow click interval works best and looks more natural.
Step 4: Position Your Mouse
Place your mouse somewhere safe:
- Empty area of the screen
- Chat box
- Inventory area
Avoid clicking buttons that buy items or leave the game!
Step 5: Start the Auto Clicker
- Activate the auto clicker
- Minimize Roblox if needed
- Your clicks will keep you active and prevent Error 278
You can now AFK for hours without being disconnected.
Best Games to Use AFK Auto Clicker In
Auto clickers work especially well in:
- Simulator games
- Tycoon games
- AFK reward games
- Idle farming games
- Waiting lobbies or queues
Note: Some competitive or anti-cheat games may not allow auto clicking, so always check the game rules.
Alternative Ways to Avoid Error 278 (No Auto Clicker)
If you don't want to use an auto clicker:
- Move your character every 10–15 minutes
- Press keys occasionally
- Use in-game AFK buttons (if available)
- Open and type in chat periodically
These methods work, but auto clickers are the easiest and most reliable.
Is Using an Auto Clicker Safe in Roblox?
Generally:
- Roblox itself does not ban for simple clicking
- Most issues come from individual game rules
Use auto clickers only for:
- AFK staying active
- Idle farming (not exploiting)
Avoid scripts, exploits, or macro abuse — those can lead to bans.
