Error: "This site can’t be reached" after change domain [Solved]

First of all I'm using Google cloud platform with openLiteSpeed, wordpress site.
I'm on fly more than a year with domain.
Today I changed my domain and from this moment I can't enter to my site even if I'm using the External IP of my instance.
For now I deleted all my records in DNS section to try to handle this problem and still it does not work.
I also changed the virtual mapping on Listener section in openLiteSpeed dashboard.
I don't have idea what todo next, I try to solve it more than 5 hours.
Any suggestions how can I solve it ?

Edit: Solved you can delete it !
