IP Nat cannot add new configuration

Hi,

I installed new server and cannot use nginx reverse server. When i try to start always get error. My old server have ip problem, so i installed new one but no have add new configuration button in ipnat area.

I installed 3 times for check that (maybe something wrong so i clean install again and again) but always same.. What should i do? What i miss?

you need advanced knownledge to setting nginx... better try nginx+apache.. btw if you are free cwp user. u have limited option for the webserver

I tried new installation today and again its the same. I have already another server and i have add button here in the image..

no have this button and i cannot add any nat ip in the table. If i can add this, i can set my server options to the nat behind working.. how can i solve this problem or else, how can i find this file for add manually in terminal?
