ANSWERED OpenVPN connection issue in Malaysia - Stuck on IPv6

[Fyaskass 0]

Voici la version en anglais que vous pouvez poster sur le forum d’AirVPN :

Hello everyone,

 

I’m experiencing an issue with my OpenVPN connection using the Eddie client (version 2.21.8) on macOS 15.0. I’m currently in Malaysia, and it seems that my network is stuck using IPv6. Unfortunately, I don’t have any way to use IPv4, which appears to be causing problems with establishing a stable VPN connection.

 

When I try connecting to various servers (such as Achernar in Switzerland and Alula in Sweden), I get the following error in the OpenVPN logs:

 

OpenVPN > write UDP: Network is unreachable (code=51)

 

The authentication process works fine, but once the connection attempts start, I encounter this error indicating that the network is unreachable. The Eddie client tries to restart the process, but it fails each time.

 

Has anyone else experienced this kind of issue when being forced to use IPv6? Are there any specific settings I can tweak to bypass this problem or force the use of IPv4 despite these restrictions?

 

Thank you in advance for your help.

 

Best regards,

Hello!

We asked for a system report, which provides relevant information in addition to the log. From the log, anyway, we can see that you picked a connection on the IPv4 layer; however, you should try one on IPv6 since you don't have IPv4 connectivity from your ISP.

• from Eddie's main window select Preferences > Networking
• set the Protocol used for connection combo box to IPv6 only
• click Save

Test again connections and send us a system report generated by Eddie if the problem persists.

Kind regards
