ipv6 command failed: returned error code 1

[Equityc 6]

I am getting the IPv6 error again since this morning (Eddie 2.20.0).
 

OpenVPN > ERROR: Windows route add ipv6 command failed: returned error code 1
[...]

Only way around is to block IPv6 -> preferences -> networking -> set 'Layer IPv6' to 'Block'
