Wordpress multisite + domain mapping not working

Hi dears,
I installed wordpress multisite + wpmudev domain mapping plugin . but domain mapping does't work properly . i search a lot and test any way for this but ...

My steps was here :
1.Create vps with ip :
2.install WHM/cPanel on this
3.install wordpress
4.enable server wildcard for subdomain support then enable wordpress network
5.create subdomain *.mynetwork.tld and it's create an A record automatically
6.add below ns for mapping domain (amoozgar.net) :

ns1.amoozgar.net with sub ip :
ns2.amoozgar.net with sub ip :

but not work
I was wrong in ?

My server ip is :
My domain that i set nameservers to above ip : amoozgar.net

in a topic i see that for this work dedicated IP should be pointed to network site

Thank you
