Why do I get error 279 on good WiFi?

Strong WiFi signal does not equal stable connection. You can have full bars but still have packet loss or high latency which causes error 279. Use a free tool like pingtest.net to check for packet loss. Switching to Ethernet almost always resolves this.

Does error 279 mean Roblox is down?

Usually not. Error 279 is almost always a network issue on your end — firewall, VPN, DNS, or connection instability. Check our Roblox Status page to rule out a server-side issue before troubleshooting your network.

How long does error 279 last?

If the cause is on your side it can be fixed immediately using the steps above. If it is caused by a Roblox server issue it typically resolves within 15 to 60 minutes. Firewall and DNS fixes are permanent once applied.

Can my internet provider cause error 279?

Yes. Some ISPs block or throttle certain gaming traffic on specific ports. If you get error 279 consistently despite trying every fix contact your internet provider and ask about gaming port access. Changing DNS to 8.8.8.8 often helps with ISP routing issues.
