OpenVPN Server setup no default gateway

Hi,

I am new to the RouterOs and have some difficulties setting up OpenVPN server on device hXE RB750Gr3

The issue is that I am able to connect via OpenVPN client I get the IP from correct range, but no gateway is assigned to OpenVPN NIC and the connection is nonstop restarting:

Connection reset,restarting [-1]

Attaching the server setup plus client config and logs from the client.

Trying already for more than two weeks without success :-(, so any help if appreciated.
