I do all of these works but the problem does not solve yet...

This is the last step in the support document that I provided you with.

If you’ve tried all of the above steps and you still can’t connect, contact Apple Support.

This is not Apple Support, this is a user to user support forum, and Apple does not participate here. Use the link to contact Apple support.

See this support document for other troubleshooting steps. If you can't connect to the iTunes Store, iBooks Store, or App Store - Apple Support

I can not sign in to app store with my apple id on my new iphone.

Why not? What happens when you try? Do you receive an error?

Make sure that you are connected to the internet on the device, either wi-fi or cellular.
