Step-by-Step Fixes
Method 1: Check Your Internet Connection
Step 1: Restart your modem and router. Unplug them from the power outlet, wait 30 seconds, and plug them back in.
Step 2: Run a speed test to ensure you have sufficient bandwidth and low ping. If your speed is significantly lower than expected, contact your ISP.
Step 3: If using Wi-Fi, try switching to a wired (Ethernet) connection for a more stable connection.
Method 2: Check Roblox Server Status
Step 1: Visit the Roblox status page (status.roblox.com) or search online for Roblox server status updates.
Step 2: If there is a known outage, wait for Roblox to resolve the issue. There is nothing you can do on your end until the servers are back online.
Method 3: Configure Firewall/Antivirus
Step 1: Add Roblox to your firewall's allowed list. This usually involves going into your firewall settings and creating an exception for Roblox.exe and RobloxStudioBeta.exe.
Step 2: Temporarily disable your antivirus software to see if it is interfering. If the error disappears, configure your antivirus to allow Roblox.
Step 3: Scan your computer for viruses. A virus may be interfering with the Roblox execution.
Method 4: Reinstall Roblox
Step 1: Uninstall Roblox completely from your computer.
Step 2: Download the latest version of Roblox from the official website (roblox.com) and reinstall it.
Step 3: Restart your computer after installation.

Step 2: Restart your browser and try joining the game again.
