I have migrated the magento 2 code to a different server and setup the same codebase on my local/wamp server.

The admin pages are not showing any data but on my local/wamp server all admin pages like Sales Order are displaying orders.

After debugging the sales order page I have found that admin order ajax request on wamp server is returning json but on the different server it is returning html.

On Local/Wamp server below request is returning json data for orders:
http://abc.local/admin_4ajzfg/mui/index/render/key/d1ee5ae1cb3aa5c668504a2d52544fb6abbb33d4f5dd16c1c9ea2610d6b7d3b9/?namespace=sales_order_grid&search=sand&keywordUpdated=false&filters%5Bplaceholder%5D=true&paging%5BpageSize%5D=20&paging%5Bcurrent%5D=1&sorting%5Bfield%5D=created_at&sorting%5Bdirection%5D=desc&isAjax=true

On a different server the below request is returning html data:
https://abc.test/admin_4ajzfg/mui/index/render/key/24b04907fe1ae7ed4540d48e6515fb3e39978687ebc0c93b3874ddd2bbbda7c7/?namespace=sales_order_grid&search=sandeep&keywordUpdated=false&filters%5Bplaceholder%5D=true&paging%5BpageSize%5D=20&paging%5Bcurrent%5D=1&sorting%5Bfield%5D=created_at&sorting%5Bdirection%5D=desc&isAjax=true
