VPN and proxy protocol guides: setup, safety and troubleshooting
To connect an OpenVPN profile, start with the Windows instructions, Linux instructions or iPhone setup. To inspect a file first, use the .ovpn reading guide and config validator. If the client asks for a password or reports AUTH_FAILED, use the public-profile authentication checklist.
Understand OpenVPN, VLESS, Trojan, VMess, Shadowsocks, Hysteria2, TUIC, WireGuard and IKEv2, compare proxy and full-VPN designs, inspect configuration fields, find checked servers and solve connection problems.
