Possible Unhandled Promise Rejection (id: 0) Error: timeout of 0ms exceeded

I want to show the total number of connections I have using the API I created, but when I run with the mobile project, the results show only '0' and show this error message. It should automatically display the number of connections on the screen, I already tested it with the web application and it works, the problem persists only in the mobile version. In the api.ts file the URL is in this format because I am simulating the mobile application on an iOS device with a DevTools connection through the Tunnel.

My api.ts for connetion with api

import axios from "axios";

const api = axios.create({
    baseURL: "http://y7-xkq.anonymous.mobile.exp.direct:3333",
});

export default api;

const [totalConnections, setTotalConnections] = useState(0);

    useEffect(() => {
        api.get("connections").then((response) => {
            // console.log(response);
            const { total } = response.data;

            setTotalConnections(total);
        });
    }, []);

<Text style={styles.totalConnections}>
    Total de {totalConnections} conexões já realizadas{" "}
    <Image source={heartIcon} />
</Text>
