About this tag
This tag covers troubleshooting built-in Windows 10 and Windows 11 VPN connections that fail to connect. The content focuses on verifying that a VPN profile matches the provider's required server address, tunnel type, and sign-in method, and on restoring Windows services responsible for Remote Access and IKE/IPsec negotiation. It addresses common protocols like IKEv2, L2TP/IPsec, SSTP, and PPTP, and advises against resetting the network stack or deleting profiles prematurely. The guidance is specific to the built-in Windows VPN client and does not apply to third-party VPN apps with their own adapters and services.
