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.
