Quick Summary
Error code 1105 in Roblox typically indicates a problem connecting to the specific game server you are trying to join. This connection issue can stem from various network and platform-related factors.
Common Causes
- Roblox Server Issues: The Roblox game server itself might be experiencing outages, maintenance, or other technical problems that prevent players from connecting. These issues are generally outside the user's immediate control.
- Network Connectivity Problems: Problems with your own internet connection, such as a weak Wi-Fi signal, temporary network outage, or firewall restrictions, can prevent Roblox from establishing a stable connection to the game server.
- Conflicting Programs: Certain security software or other applications running on your computer can interfere with Roblox's ability to connect to its servers.
- Roblox Client Issues: A corrupted or outdated Roblox client installation can also lead to connection errors. This may include outdated files preventing a consistent connection.
