What This Code Means
Error 812 is commonly associated with VPN connections rejected due to server-side network policy settings. The VPN server may require specific authentication methods, user groups, device compliance, or encryption settings.
Where Users Usually See This Code
- Corporate VPN access attempts
- After changes to account permissions or VPN policy
Why This Code Appears
- User account is not permitted by VPN policy
- Authentication type or encryption requirements do not match
- Network policy server rules changed
What Typically Happens Next
- The VPN connection is rejected until policy or client settings are corrected
What This Code Is Not
- It is not a router Wi-Fi signal issue
- It is not always caused by an incorrect password
Troubleshooting Checklist
- □ Confirm with your admin what VPN type and authentication method is required
- □ Verify your account is authorized for VPN access
- □ Check whether device compliance or MFA is required
Notes And Edge Cases
This is typically resolved by policy changes on the VPN server rather than local router changes.
