rparkinson 0 Posted ... Hi, I am unable to connect to an AirVPN server. It appears to be an issue with the IPv6 route. I get the following error: "OpenVPN > ERROR: Windows route add ipv6 command failed: returned error code 1" I have not changed any settings etc so I do not understand why this is now happening. I have attached my logs for a typical connection attempt below. Any help would be really appreciated. Thanks. . 2020.09.06 17:43:38 - Eddie version: 2.18.9 / windows_x64, System: Windows, Name: Windows 10 Pro, Version: Microsoft Windows NT 10.0.18363.0, Mono/.Net: v4.0.30319 . 2020.09.06 17:43:38 - Command line arguments (1): path="home" . 2020.09.06 17:43:39 - Profile path: C:\Users\User\AppData\Local\Eddie\default.profile . 2020.09.06 17:43:39 - Reading options from C:\Users\User\AppData\Local\Eddie\default.profile . 2020.09.06 17:43:44 - Tun Driver - 0901: 9.24.2; wintun: Not found . 2020.09.06 17:43:44 - OpenVPN - Version: 2.4.8 - OpenSSL 1.1.0l 10 Sep 2019, LZO 2.10 (C:\Program Files\AirVPN\openvpn.exe) . 2020.09.06 17:43:44 - SSH - Version: plink 0.67 (C:\Program Files\AirVPN\plink.exe) . 2020.09.06 17:43:44 - SSL - Version: stunnel 5.40 (C:\Program Files\AirVPN\stunnel.exe) . 2020.09.06 17:43:44 - curl - Version: 7.68.0 (C:\Program Files\AirVPN\curl.exe) I 2020.09.06 17:43:49 - Ready . 2020.09.06 17:43:51 - Collect information about AirVPN completed I 2020.09.06 17:43:53 - Session starting.

OpenSourcerer 1435 Posted ... You are the second one I see with exactly the same thing recently. Error when setting, then failing to check v6 routes. There is no solution yet. Workaround is disabling v6 for now, of course (Preferences > Networking > Set Layer IPv6 to Block). You can upload or paste the support file here if you're overly bored (Logs tab > lifebelt icon), but I don't think it will help much.

The actual official cause is lack of IPv6 support either at system level or in any of the network interfaces, including the tun/tap one. It has been verified several times. Should you find cases for which IPv6 layer needs a block inside Eddie preferences even when IPv6 is fully supported by the system and is enabled on all network interfaces, including TAP-Windows or wintun, please report to Clodo.

xm6g6 0 Posted ... I've been using Eddie 2.20 for many months flawlessly, and yet I just tried to connect to a server and I got the same message. OpenVPN > ERROR: Windows route add ipv6 command failed: returned error code 1 I certainly haven't changed anything (I really don't know how!) I should add that the previous message by Staff utterly and completely goes over my head, and I haven't a clue as to what or who Clodo is. Quote Share this post Link to post
