Starting a few updates ago OpenVPN client fails to remove routes on my PC.
It happens with severl servers and server config does not matter (of course it should include route change).
My OS is Windows 10 Pro x64 21H1.
As an example, client.conf:
Code: Select all
client
dev tap
;dev-node MyTap
proto udp
remote aaa.com 31571
float
ncp-ciphers AES-128-GCM:AES-256-GCM:AES-128-CBC:AES-256-CBC
cipher AES-256-CBC
keepalive 15 60
auth-user-pass
mute-replay-warnings
remote-cert-tls server

As I said the same situation happens for any connection with different servers so I suspect it is pure client issue. Also please note this issue never happens two or three releases ago.
What is wrong?
