This material explains lawful network security and configuration scenarios. Follow the rules that apply in your location.
1. Get a connection key
Choose the period and device count in the Flex-VPN Telegram bot. After activation, the bot provides a profile or connection link. One key per device makes access management and troubleshooting much clearer.
The key contains private connection details. Do not post it in chats or paste it into random profile-checking websites.
2. Install the client
Use AmneziaVPN for AmneziaWG. Happ or another explicitly compatible client can import VLESS + Reality. Install apps from official stores or the Flex-VPN download page.
Pause another VPN or local filtering app during the first test to avoid competing routes.
3. Import the profile
Open the connection link or copy the key and select clipboard import. Approve the operating system VPN configuration, save the profile and connect.
Do not edit the server address, port or long parameter strings manually. One invisible space can invalidate a profile.
4. Verify the result
Open several sites, check the public IP and switch between Wi-Fi and mobile data on a phone. On a work laptop, also test a video call and recovery after sleep.
A connected status only proves that the local interface started. A real browsing check confirms that traffic can complete the route.
5. Configure behavior
After the basic test, enable auto-connect, always-on mode or split routing as needed. Add rules gradually and verify after each change.
When replacing a phone, test the new profile first and revoke the old key afterward. This avoids downtime and abandoned active devices.
Frequently asked questions
What is a VPN key?
It is a string or link containing connection and authorization details. Protect it with the same care as a password.
Why will a key not import?
Confirm that the client supports its protocol, the complete link was copied and the app is current.
Can a profile move to a new device?
Yes, but issuing a separate key and revoking the old one after testing is easier to manage safely.
