OpenVPN works on Android but not in Windows

[ejvl]

Hi,
Yesterday i've installed Opnsense on my NUC and all works fine, great product.
I've issues with OpenVPN.
I've followed this instruction: https://www.youtube.com/watch?v=ocGAcZD8qYo

Now, I've export the setting, VPN, Client Export, export the settings/certificatie from the linked user.


I've imported this file in my Android phone, installed OpenVPN and all works fine, I can connect when I'm not on WIFI, can reach my LAN-devices.

Now I've a Windows 10 machine, remote, install OpenVPN, import exact the same file but cannot connect.

I've turned off the Windows firewall but no changes.

The file I've exported from OPNsense is a single .ovpn file with the certificates included and the file is correct I think because it works fine on my Android phone.

Any idea?

Thanks

I've solved it, the time in Windows was wrong....
