How to fetch private network using android and react-native

I'm currently trying to access local network (192.168.1.**) from my android react-native application.

I've no access to the internet but only some website from my company. (I can access them throw chrome, opera, edge but not throw firefox).

When I try to fetch the url "constellation.tech" (192.168.1.223) (which is one of the accessible website) I got this error :

TypeError: Network request failed
        at XMLHttpRequest.xhr.onerror (7d73db73-6dce-4f17-a442-ddd610de0c2a:24524)
        at XMLHttpRequest.dispatchEvent (7d73db73-6dce-4f17-a442-ddd610de0c2a:29723)

I've already search on some post, most of them are about fetching localhost, I've tried some workaround like using axios, set :

<application
   ...
  android:usesCleartextTraffic="true"
 ...>

to ./android/app/src/main/AndroidManifest.xml.

Does someone have any information, or a solution to this problem ?

Thanks for reading :)
