TAP-Windows Adapter Windows 10 DHCP error

[mpratt14]

(copy of ​https://github.com/OpenVPN/tap-windows/issues/9)

Windows 10 64-bit
Openvpn GUI 11.13.0.0
Openvpn 2.4.7

The error is
Initialization Sequence Completed With Errors ( see ​http://openvpn.net/faq.html#dhcpclientserv ) MANAGEMENT: >STATE:1559241905,CONNECTED,ERROR,10.8.0.2,xx.xx.xx.xx,9090

The very first connection to the server is successful, and the window minimizes itself as expected. If I reconnect, or disconnect and connect, every attempt after that fails.

I found an old forum post on this

They have absolutely no solution to this, and I have yet to find an problem with my config.

All non-Windows clients work fine without this issue

Workarounds:

reinstalling the TAP adapter with the included scripts (or the one in the forum, or one that resets all adapters)

going to "Network Connections" in control panel (ncpa.cpl) and disable TAP adapter, reenable TAP adapter, reconnect

add the directive to the client config ip-win32 manual and set the IP, Subnet, Gateway, manually (again using ncpa.cpl)

The first 2 of my workarounds have to be done EVERY SINGLE TIME one wants to connect or reconnect to the VPN. The third one is an almost permanent fix, but if the server gives you a different IP, you have to do extra work...

please post a log file with --verb 4 so we might get an idea what's special about your setup.

Please post the full log (verb=4) for a connection that succeeds followed by the one that shows the error.

When the connection errors, does manually setting the address work without resetting the tap adapter? If yes this has to be something not letting the address assign via dhcp -- as it succeeds the first time, I have no idea what that could be.

closing this ticket. If we have no information required to debug this, we can't help.
