1) I used a shapeshifter-dispatcher with obfs4 and a clean openvpn2 server behind it as a server. 2) Compiled that PR with -DOPENVPN_PLUGGABLE_TRANSPORTS flag. 3) Wrote two classes, light c++...
Problem was in [Shapeshifter-obfs4-OpenVPN-Transport-Plugin-Cgo](https://github.com/OperatorFoundation/Shapeshifter-obfs4-OpenVPN-Transport-Plugin-Cgo ), after rewriting _Obfs4_read_ It works perfectly
Some problem with windows service, looks like it already running. 1) Try to reboot your PC. 2) Delete all AmneziaVPN service and install it again.
Do you have another installed VPN like Mullvad or Mozilla VPN?
Please check new release [4.3.0.0 ](https://github.com/amnezia-vpn/amnezia-client/releases/tag/4.3.0.0). Does it reproduce with 4.3.0.0?
> ErrorCode: 101. Internal error. This means some problem with the connection to AmneziaVPN-service. What OS do you use? You can try to reinstall AmneziaVPN and then reboot PC.
Looks like IPv6 is disabled in your system. Please look at [https://www.reddit.com/r/AmneziaVPN/comments/16uspfe/comment/k781t8y/](https://www.reddit.com/r/AmneziaVPN/comments/16uspfe/comment/k781t8y/).
It happens what you have already started windows service. We did some fix around this issue #791 and #738 . What AmneziaVPN do you use?
Please attach AmneziVPN log file from Linux client.
