OPENVPN turris-turris connection

i am trying to use OPENVPN client registration on on 1st turris + client settings on 2nd turris to connect these 2 networks via vpn. If i load config file and network is restarted on turris automatically, it stopps working completely. Restart does not help, not only VPN, aby complete internet stops working. I have to delete client specification file from turris menu in reForis to make internet working back. I realized, that when openvpn client specification file was loaded, Firewall Status page is completely empty, no rules are displayed. When i delete config file from turris, firewall status pages contains standard info.

What to check?
