I have a weird issue, I got a sandbox wss://v2.sandbox and https://v2.sandbox links every request on the API Rest, and the socket server works fine in Wifi but when I want to try the App in 4g no a single request work. Same behavior with my browser, impossible to get access to the dashboard, API rest, or socket server with a shared connexion but work in wifi.
I checked the banip list - clear I checked my DNS - clear (using the DNS of Google)
My partner who made the BO think that could be the app but I test several free APIs, socket servers anything works still no access to his BO.
I would appreciate some idea on this issue that is out of my spec. I'm using a Fresh install of RN I test both fetch API and Axios same results. RN Version: RN 63.4
