CHOOSING THE RIGHT PROTOCOL

Quick Protocol Map
SSH:
Best for manual login apps that ask for host, username, password, and port.
VLESS:
Best when the client can import a URI or Xray-style profile.
Hysteria:
Best when the client explicitly supports Hysteria links or configs.
WireGuard:
Best when you want a config file or QR code import.
OpenVPN:
Best when the client expects a standard
.ovpn file. Manual Vs Imported
If your app imports links or config files cleanly, start there. Imported profiles reduce typing errors and make it easier to reuse the same account across devices. If your app is older or more manual, SSH and some OpenVPN setups can still work well, but they require more careful entry of every field.
A Simple Decision Rule
Choose the protocol your client already supports natively. That rule is simple, but it solves most setup failures: VLESS if you want a URI, WireGuard if you want a QR or config file, OpenVPN if the app wants
.ovpn, Hysteria only when the client explicitly lists it, and SSH when the app expects manual credentials. What Not To Do
Do not force one protocol into another client just because the names look similar. A good import on the wrong app is still the wrong app. If the page and the client disagree, the client's supported format is the one that matters.
