In app purchase not working


My App is live with auto-renew InApp purchase. before Everything was working fine then a user complained that when they click on Buy Button Nothing is happening.
i have not changed any code and also i did not upload new build.My product is also Approved on Appstore Connect.
i did not change anything on product but app is now suddenly dead. no info also available . dont know what to do

I have encountered the same issue. Anyone have any insights?
