Quick Summary
Error code 279 on Roblox typically indicates a disconnection from the game server. This disconnection can occur due to various issues on the user's end, the Roblox server's end, or somewhere in between.
Common Causes
- Network Connectivity Issues: A weak or unstable internet connection is a common cause. Intermittent connectivity, packet loss, or high latency can all lead to a disconnect.
- Firewall or Antivirus Interference: Firewall or antivirus software might be blocking Roblox's access to the internet. This prevents the game from maintaining a stable connection with the servers.
- Roblox Server Problems: Roblox servers may be experiencing downtime, maintenance, or unexpected outages. These issues can cause widespread disconnections.
- Outdated Roblox Client: An outdated version of the Roblox client can sometimes be incompatible with the server, leading to disconnections.
- Conflicting Applications: Other applications running in the background might be consuming excessive bandwidth or interfering with Roblox's network connection.
Step-by-Step Fixes
Method 1: Check Your Internet Connection
Step 1: Verify your internet connection is stable. Try visiting other websites or using other online applications.
Step 2: Restart your modem and router. This can often resolve temporary connectivity issues.
Step 3: If using Wi-Fi, try switching to a wired (Ethernet) connection for a more stable connection.
Step 4: Run a speed test to ensure you have sufficient bandwidth and low latency.
Method 2: Disable Firewall or Antivirus Temporarily
Step 1: Temporarily disable your firewall or antivirus software. Note: Be aware of the security risks when disabling these.
Step 2: Launch Roblox and see if the issue is resolved.
Step 3: If the issue is gone, add Roblox as an exception in your firewall/antivirus settings to prevent future blocks. Re-enable your firewall/antivirus after.
Method 3: Update Roblox
Step 1: Close Roblox completely.
Step 2: Re-launch Roblox. The client should automatically check for and install any available updates. Ensure you are patient while Roblox installs updates.
Step 3: If automatic updating fails, try reinstalling Roblox from the official website.
Method 4: Close Unnecessary Applications
Step 1: Close any applications that are not essential and might be using a lot of internet bandwidth (e.g., streaming services, large downloads).
Step 2: Use Task Manager (Windows) or Activity Monitor (macOS) to identify and close applications with high network usage.
Method 5: Flush DNS and Reset TCP/IP
Step 1: Open Command Prompt as administrator (Windows).
Step 2: Type the following commands, pressing Enter after each one:
ipconfig /flushdnsnetsh winsock resetnetsh int ip reset
Step 3: Restart your computer.
