Who to add it to your system or browser as a trusted certificate?

I cannot make requests when I compile for production and sign the application to upload it…
the mistakes are:
IOS:

PI error: <_UIKBCompatInputView: 0x10320f8f0; frame = (0 0; 0 0); layer = <CALayer: 0x28073b9a0>> returned 0 width, assuming UIViewNoIntrinsicMetric

Android:

E/chromium: [ERROR:ssl_client_socket_impl.cc(969)] handshake failed;
