Step 5: Check Firewall and Antivirus Settings
Sometimes, security software can block legitimate network or system operations, causing ERROR_270.
- Temporarily disable your firewall and antivirus:
- Open your antivirus interface and turn off real-time protection.
- Go to Windows Defender Firewall in Control Panel and turn it off temporarily.
