Understanding Error Code 279 and ID=17
Before diving into solutions, let's understand what this error actually means. Error code 279 is a connection error that prevents users from joining game servers, with ID=17 being an internal Roblox identifier pointing to failed attempts to establish a server connection due to missing or blocked port access.
What Causes Error Code 279?
The error can be triggered by multiple factors:
Network Connectivity Issues: If you have a sluggish internet connection, you may get an error message. This error may appear if your internet connection is too sluggish to support the game's objects.
Firewall and Security Software: Windows Firewall or third-party antivirus programs may block Roblox from establishing necessary connections
NAT Type Restrictions: Most online games require an open NAT type of internet. Network Address Translation comes in three forms: open, strict, and moderate. Strict NAT types can prevent connection to Roblox servers.
Corrupted Game Files: Damaged or incomplete installation files can trigger connection failures
Server-Side Issues: Sometimes specific game servers are overloaded or experiencing technical difficulties
Browser Extensions: Ad-blockers and other browser extensions can interfere with Roblox's web version
DNS Cache Problems: If this catalog receives incorrect entries or is corrupted, you will not be able to connect to some servers, which can lead to Roblox error code 279.
Platform-Specific Error Behavior
Error Code 279 manifests differently across platforms:
Windows PC: Most frequent occurrence due to complex firewall and antivirus configurations
Mobile (iOS/Android): Usually related to app permissions or mobile data restrictions
Xbox: Often caused by NAT type issues or parental controls
Mac: Similar to Windows but with different firewall settings
Browser-Based: Typically related to extensions or browser security settings

Frequently Asked Questions
What exactly is Roblox Error Code 279?
Error code 279 in Roblox relates to your device's connectivity to the game server. You may often see the error code mentioned alongside the "ID=17 Failure" message. It prevents the Roblox client from loading data from game servers.
Is Error Code 279 permanent?
No, Error Code 279 is not permanent. It's a temporary connection issue that can be resolved by following the solutions in this guide. Most players fix it within 10-30 minutes of troubleshooting.
Why does Error 279 only happen in certain games?
Some Roblox games have more complex networking requirements or poorly optimized server code. Games with high player counts, complex physics, or custom networking scripts are more likely to trigger Error 279.
Can my account be banned for getting Error 279?
No, Error Code 279 is purely a technical connection issue and has nothing to do with account violations. Your account is safe.
Will using a VPN fix Error Code 279?
VPNs rarely fix Error 279 and often make it worse by adding another layer of complexity to your connection. Only use a gaming-optimized VPN if you're certain your ISP is blocking Roblox traffic.
How long should I wait before trying another solution?
Give each solution 5-10 minutes to take effect, especially network-related changes that require time to propagate. Restart your device between major changes.
Why do I get Error 279 on Wi-Fi but not ethernet?
Wi-Fi connections are less stable and more prone to interference than ethernet. Factors like distance from router, wall interference, and network congestion affect Wi-Fi more than wired connections.
Can Error 279 damage my computer or device?
No, Error Code 279 is just a connection error and cannot damage your hardware or software. It's completely safe to troubleshoot.
Should I contact my ISP about Error 279?
Only contact your ISP if you've confirmed they're blocking gaming ports or if your internet speed is consistently below 4 Mbps. Request port forwarding or NAT type changes if needed.
Is there a difference between Error Code 279 and ID=17?
Error Code 279 and ID=17 refer to the same connection problem. Error Code 279 is the general error number, while ID=17 is Roblox's specific internal identifier for port-related connection failures.
Conclusion
Roblox Error Code 279 (ID=17) might seem overwhelming at first, but with systematic troubleshooting, it's completely fixable. Start with simple solutions like checking server status and restarting your router before moving to advanced fixes like port forwarding and DNS configuration.
