Problem reading page

I'm reading data from a page.

But I would like to read this data every 3 seconds or every time the node has finished reading the data.

I'm using this function here:

const getScript = (url) => {
    return new Promise((resolve, reject) => {
        const http = require('http'),
            https = require('https')

        let client = http

        if (url.toString().indexOf('https') === 0) {
            client = https
        }

        client.get(url, (resp) => {
            let data = ''

            // A chunk of data has been recieved.
            resp.on('data', (chunk) => {
                data += chunk


            })

            // The whole response has been received. Print out the result.
            resp.on('end', () => {
                resolve(data)
            })

            resp.destroy()
        }).on('error', (err) => {
            reject({error:  err})
        })
    })
};

In the first moments he reads, but then he starts giving the message below

{ Error: read ECONNRESET
       at TCP.onread (net.js:656:25) errno: 'ECONNRESET', code: 'ECONNRESET', syscall: 'read' } }

Is it because the page gets busy?

Thanks for the help
