Always Network Request Failed in React Native Android App

The React Native App(Android) does not work on the any devices(mobile device and emulator). I always see network request errors. So I added the network_security_config.xml file to the xml holder, but it still doesn't work. Backend url is 'https://prvmsg.com' I've been grappling with this problem for a week. Please help me.

I am going to pay 100$ to developer to resolve this problem.

Auto Bid will be disappeared.
Please start with 'I can resolve this problem within a day.'
