Power Bi Desktop not showing values in some columns after moving the cube to PROD environment

Hello Community, it would be really great someone out here helps me.

I have moved my Cube [Analysis Services Tabluar Project] (made in visual studio) from UAT to PROD, data is shown properly in in power bi reports for UAT but as soon as move the cube to PROD environment most of the columns are blank. I have even checked each and every relationship but still the problem persists. It's my humble request to help me out. If you need any more information do tell I'll provide the info.

The data is shown properly in both the environments i.e is UAT and PROD.
PS: I have been using 'Live Connection' for the report
