Jdev issue with Anyconnect VPN4.10 java.net.SocketException:Permission denied:connect

Ken Mills

Greetings,

*At the bottom of the intro will be the errors and data i have collected.*

Java Version: 1.8.0_311

Oracle: 10.1.3.x

Anyconnect: 4.10.01075

OS: Windows 10

Hopefully someone can help me here ive spent a few weeks troubleshooting an issue that is impacting a large group of developers at my company whom received new laptops but cannot connect with jdev using localhost on Cisco Anyconnect VPN version 4.10.01075

To make it stranger, the connection on the new laptops works on the network proper and off VPN as well as on standard external connection. The old laptops with mirrored configurations has no issue with the former(works internal, vpn and external)

The software versions of Jdev, Java, Oracle and Anyconnect are the same between the new and old units and there is transparent proxy settings here as i was looking at a similar exact issue that was closed with no resolution(see: https://community.oracle.com/tech/developers/discussion/3993565/unable-to-run-applications-in-jdeveloper-with-anyconnect-vpn )

Any help or guidance would be incredibly appreciated on this, hopefully i provided enough data to start this off!

Hello @Ken Mills

It seems i am having a similar problem!!

Were you able to find a solution for this?

thank you

dvohra21

Have the suggestions in the message dialog been tried?

Elio Khattar

hi @dvohra21

Not from my end no.

Will try to have a look, but i guess it will rather slowdown the error message to appear since we increased the timeout,

I found solution from metalink;

Unable To Run Applications In JDeveloper With AnyConnect VPN (Doc ID 1671579.1)

but it's not working, if any one find another solution please let me know.

dvohra21

What is the jdeveloper version? It is a connectivity issue. Any Connect VPN may not be supported, or if supported some permissions need to be set.

The Unable To Run Applications In JDeveloper With AnyConnect VPN (Doc ID 1671579.1) is for jdev 10g, but could still be relevant. What was tried from the link? All suggestions? Was a "loopback adapter" installed as suggested, or were files in the persistence\ dir deleted?

Hello

I was able to workaround the issue by using the Cisco Any Connect VPN client from the MIcrosoft Store instead of the standalone cisco any connect client which comes in a separate installer.

From the VPN on the windows store, you setup the VPN connection from the WINDOWS VPN Settings.
