I have only username, password and server address of my vpn, How I can create a configuration profile?

I used to configure my profile - Imazing profile editor, and configured my profile - but it doesn't work too, my vpn works, only when I press add VPN Configuration in my settings, set description, server name, remote id (the same value as the server name), username and password - in that case it works fine

I have founded an error - I need set my ikeSecurityAssociationParameters.diffieHellmanGroup = .group2, it's veird (because as default this value is equal 2, but I need set it explicitly) now it's work
