Roblox Error 277: when the game disconnects
Error 277 often appears as a disconnect during gameplay. If the browser works but Roblox drops, the cause may be unstable routing, DNS, overloaded network or a VPN client conflict.
Common causes
packet loss or weak Wi-Fi
two VPN or proxy apps running at the same time
outdated Roblox client or corrupted cache
ISP route to a specific game server
How to check
1
Close other VPN and proxy apps.
2
Update Roblox and restart the device.
3
Test the game on another network.
4
Refresh WersidePN subscription and reconnect.
Common questions
Should I switch VPN providers immediately?
First check the network, client and subscription. Switching makes sense only if the error repeats on multiple networks and devices.
