Checkout page is scrolling and not redirecting to the thank you page but the order shows into woocommerce orders

Question

I have the website in wordpress, when i try to order on this website, it scrol on the checkout page and didn't place order and didn't go to the thank you page, but order is shown on the orders section in woocommerce. But when i use this same backup of this website into local host, it works and it smoothly procede with the order in checkout page, when I select cash on delivery on the checkout page and procede further, it scrol and few seconds and redirect me to the thank you page and shown the order into woocommerce orders that means there're no plugin, theme conflict and working well on the localhost, but it is causing issue on live server which is hostinger's service.

Note: I'm using wordpress CMS, woodmart (prebuilt) theme, elementor, woodmart core plugin and woocommerce plugin

I have implemented its backup into localhost, it start working, then got backup from localhost and applied on the live server but it didn't worked. Also, I tried to increase its PHP limits, maxupload size and other limits but it didn't worked.
