Why react native swears at the certificate?

Question

JavaScript

Good day.
I'm trying to file an application on react-native and I ran into a wonderful problem that when I try to send a request via fetch to an https domain, I get an error with a network error (while everything works fine in ios), and so on for any certificate. The same situation, if I send a request to a domain with http, but when I send a request via http to an ip address, does the answer come correctly? the question is how to fix it?

fetch('httpы://domain/api/users/support').then(function(res) {
            console.log('fetch: ', res);
        }).catch(function(error) {
            console.log('error: ', error);
        });
