In App Purchase Failed “Cannot connect to iTunes Store” error

I am facing this issue since last two months

My App is live with auto-renew InApp purchase before it was working fine then many user complained that when they click on Buy Button Nothing happens so i debug my code and run on my real device i found this error

failed SKPrdouctName
Error Domain=SKErrorDomain Code=2 "Cannot connect to iTunes Store" UserInfo={NSLocalizedDescription=Cannot connect to iTunes Store}

• i did not change any code

• i did not upload new build

• My product is also Approved on Appstore Connect

• i did not change anything on product

I already tried Restarting device , clear caches , login logout apple id still getting the same error

This is happening to many live users

I really need a solution of this
