I was disconnected after joining a gameBest match: Error 277
How to tell: The session started, then the connection to the game server was lost.
First check: Check Roblox status first, then test another experience or network before changing device settings.
Open the Error 277 guideA game will not connect or says ID 17 failedBest match: Error 279
How to tell: Roblox could not establish the game connection. This differs from a disconnect after joining.
First check: Check platform status, browser or app restrictions, firewall rules, and whether one experience or every experience fails.
Open the Error 279 guideAn update, install, or web request is forbiddenBest match: Error 403
How to tell: The request reached a service but access was refused. Repeated reinstalls are not the first diagnostic step.
First check: Confirm Roblox status and the official domain, then isolate account, network, VPN, proxy, or local install causes.
Open the Error 403 guideSeveral games or players are failing at onceBest match: Roblox status
How to tell: A broad outage can produce multiple symptoms, so a local reset may not address the cause.
First check: Compare the official Roblox status page with a second experience before troubleshooting the device.
Open the Roblox status guideI am not sure which error code this isBest match: 277 vs 279 vs 403
How to tell: 277 is a mid-session disconnect, 279 is a join that never connects, and 403 is an access or authorization refusal.
First check: Compare all three side by side, match your exact message, then open the specific code guide.
