节点，Axios请求自签名SSL，错误：在createError时node_modules / axios / lib / core / createError.js：16：15

Question

我通过Droplet（数字海洋）中的Express服务器内部的（Axios）向自签名SSL主机发出了get请求，并得到未定义的响应和错误：

如果我在本地运行它，则可以，但是当我将其放置在Server（数字海洋）中时，它将不起作用。 服务器是Ubuntu ubuntu 18.04，节点8.11.4，axios 0.18.0 示例代码：

const express = require('express');
const app = express()
const axios = require('axios')
const process = require('process')
const https = require('https')
const Querystring = require('querystring')
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

app.get('/', (req, res)=>{
    console.log('test')
    res.send('testing')
})

app.get('/api/iin/:iin', (req, res)=>{
    process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
    console.log('STAGE 1  ', req.params.iin)
    const url_iin = 'https://example.kz/services/api/Person?fioiin='+req.params.iin;
    const TOKEN = "Bearer ..."
    const instance = axios.create({
        timeout: 10000,
        withCredentials: true,
        headers: {
          'Accept': 'application/json',
          'Content-Type': 'application/json',
        },
        httpsAgent: new https.Agent({  
            rejectUnauthorized: false,
        }),
    });

    instance.get(url_iin, {headers: {Authorization: TOKEN}})
    .then(response=>{
        console.log(response)
        res.send('OK')
    })
    .catch(error=>{
        console.log(error)
        res.send('SERVER ERROR')
    })
})

app.listen(3000, ()=>{
    console.log(`listening port 3000...`)
})
