How to Fix It
-
Try joining a different server of the same game.
On the game page, click the server list to see available servers. Choose one with fewer players.
-
Check your firewall settings.
Make sure Roblox and RobloxPlayerBeta are allowed through your firewall. On Windows: Settings > Firewall > Allow an app through firewall.
-
Use the Roblox desktop app instead of the browser version.
The desktop app is more reliable than playing through a browser. Download it from roblox.com if you have not already.
-
Restart your device and router.
A fresh start clears temporary network issues that can prevent connections.
Frequently Asked Questions

Error 277 means you were connected but got disconnected. Error 279 means you could not connect in the first place. Both are network-related but have different causes.
