Finally, I had to refuse using MIkroTik. No solution. it just does not work without client certificate.

All the solutions which can be googled are for SERVER on MikroTik device, not CLIENT on it.

So, server probably ok, but client does not work currently. Pity.

Can anybody confirm that mikrotik requires BOTH user/pass AND certificate? My VPN supports only uses user/pass without certificate.

Where can I get full logs of openvpn for investigation?

Same problem here. Mullvad does not use provide/use client certificates. Only user/pass. Is mikrotik capable of running thru vpn like that?

I can not event make connection running. It just shows established when I set certificate to none. I am not hoping for any reply, considering the message date, just for record.
