Please bear with my English. I am French and I use Deepl to communicate.

For a long time I have been using NordVPN and Jdownloader2 together. So far I haven't had any problems. Recently, in an incomprehensible way, Jdownloader2 can no longer connect to the Internet. Attached is a screen shot. If I deactivate NordVPN, Jdownloader2 works.
I'm running Windows 11 Pro. I have two other machines, one running Windows 11 Family and the other Windows 10, and I have no problems on either of them.

I'm pretty sure that neither Jdownloader2 nor NordVPN are to blame. As I've completely reinstalled my machine and this incident happened during, I think it's software related, but I'm unable to specify which as I've installed a lot of them. They're also installed on the two machines that don't have any problems...!

In the absence of a solution (which would be nice) I'm looking for a clue as to what might have happened. With the logs, could you tell me why I'm having this blockage?

Thank you in advance for looking into my problem.

I transferred the logs as follows

07.11.23 02.32.13 <--> 07.11.23 02.31.21 jdlog://7688311370661/

Detail of the error I got when I tried to send the logs without disconnecting NordVPN

Try this:
Go to Settings -> Advanced Settings -> InternetConnectionSettings.preferredipversion -> Set this to "IPV4_IPV6" -> Restart JDownloader and try again

Looks like this is a common issue that also happens with other Java applications when NordVPN is used so maybe NordVPN is to blame - I really don't know.

Hello,

I've just tried it. It's still the same problem.

You're talking about Java. I do have Java installed, but on another PC running Windows 11 family, connected by WIFI on the same local network and on which Java is not installed, I don't have this problem.
I've already tried uninstalling Java but it's still the same problem. So I reinstalled Java.
On a 3rd PC running Windows 10 and connected by ethernet cable on the same local network with Java installed, I don't have this problem either. I hope the logs I've sent you can help diagnose the problem.
Best regards.
