Hello,

I recently configured my internet box 3 to allow VPN connections. I then connected from the mobile network to the VPN with my phone running Android 14, without using any particular application. The connection works fine but is marked as insecure.

Can you tell me why this connection is not secure? Does this mean that it is not encrypted or that the identification process is not secure? How to solve this problem?

Thanks in advance for the answers!

Hello Preullittie14

Could you tell us which VPN protocol you chose?

Hello Preullittie14

Who (app) says the connection is not secure? Opening the VPN and encrypting the connection between the phone and the IB3 is transparent for applications that use the internet service.

The important point is to check that the VPN activity notification is present on the phone.

If I summarize the configurations I have

Android14 VPN Setup

Name: MyVPN

Type: IKEv2/IPSec PSK
Server: name.ib3.external
IPSec identifier: myuserID
IPsec pre-shared key: abcdefghijklmopqrstuvwxyz
No advanced option

IB3 VPN Configuration

Type: IKEv2
IPSec identifier: myuserID
VPN secret question: abcdefghijklmopqrstuvwxyz

external.ib3.name defined by the IB3 DNS service

There is nothing special and the connection is always secure or does not happen if the key or protocol does not match.

Hello, I would like to understand why the insecure connection message appears?
Is this a problem with Swisscom authentication certificate not recognized by Android? Is the connection encrypted?

How do I diagnose my VPN connection?

Thank you for your detailed answers!

Hello Preullittie14

If you get the message “unsecured connection”, this indicates that your VPN connection cannot be established. The VPN option, whether on your mobile or on the Internet box, is not correctly configured. I just programmed my Samsung Galaxy XCover 4S business phone with Android 11 without any problems.

As @DanielD indicates There is nothing in particular the connection is always secure or does not happen if the key or protocol does not match.

Hello,

I have the same problem. There is a connection but it says it is not secure.

I’m running Android 13 and therefore with the IKEv2 protocol.

What’s the problem (if there is one)?

Thank you for your help and best regards.
