When to Call a Professional

Error 277 is almost always fixable by the user. However, if you have tried every step above and still cannot connect to any Roblox game, contact Roblox Support at roblox.com/support and submit a ticket with your account name, device type, and a description of the error. If the issue appears to affect all internet apps and games — not just Roblox — contact your Internet Service Provider (ISP), as you may have a line fault or a network-level problem that requires a technician.

Frequently Asked Questions

What does Roblox Error Code 277 mean?
Error Code 277 means your Roblox game client lost its connection to the game server. The disconnection can be caused by an unstable internet connection, a Roblox server outage, an outdated app version, or a firewall blocking Roblox's network traffic.
Why does Error 277 keep happening on Roblox?
If Error 277 keeps repeating, the most common culprits are an unstable Wi-Fi signal, a router that needs a restart, a firewall or antivirus incorrectly blocking Roblox, or a specific game server that is overloaded. Try using a wired Ethernet connection and clearing your Roblox cache to stop it from recurring.
Is Roblox Error 277 caused by my internet or by Roblox?
It can be either. First check status.roblox.com — if Roblox reports an active outage, the problem is on their end. If their status is normal, the disconnection is most likely related to your local internet connection, router, or device settings.
Does Error Code 277 only happen on PC?
No. Error 277 can appear on PC (Windows and Mac), iOS, and Android. The troubleshooting steps are similar across all platforms: check server status, restart the app, check your internet connection, clear the cache, and update or reinstall Roblox.
Will I lose my Roblox game progress when Error 277 appears?
Progress saved automatically by the game (such as inventory items, currency, or level data stored server-side) is usually preserved because it is stored in Roblox's cloud. However, any unsaved local progress from the current session — such as a partially completed obby or a build not yet auto-saved — may be lost when the disconnection occurs.
