SSL certificate - disable verification in axios and react

I'm trying to consume an API in my react application using axios. The API works over HTTPS with self signed certificate. So far I've got the following error when connecting:

net::ERR_INSECURE_RESPONSE
bundle.js:65253 HTTP Failure in Axios Error: Network Error
    at createError (bundle.js:2188)
    at XMLHttpRequest.handleError (bundle.js:1717)

I tried the following but without success:

import axios from 'axios';

const https = require('https');

const agent = new https.Agent({
    rejectUnauthorized: false,
});

const client = axios.create({ //all axios can be used, shown in axios documentation
    baseURL: process.env.REACT_APP_API_URL,
    responseType: 'json',
    withCredentials: true,
    httpsAgent: agent
});

export default client;

Is there any way to disable the certificate verification?

Solution 1:

Here is a way to have self-signed and accepted localhost certificates. Basically, you generate the certificate and add it to Chrome manually before using it.

Guide by Let's Encrypt: https://letsencrypt.org/docs/certificates-for-localhost/ (seems a bit advanced).

There is this answer too, that explains how to add certificate while you are at the site: https://stackoverflow.com/a/18602774
