Node JS server hosted on Elastic Beanstalk

Question

I am having a problem with my connection to Elastic Beanstalk server. I am running a server on AWS Elastic Beanstalk with a simple call as followed:

app.get('/WhatIsCool?', function (req, res) {
    res.send("You are cool!!!")
})

and on the Java side I have

public String testing() {
    try {
        URL http = new URL(urladdress + "/WhatIsCool");
        HttpURLConnection openCon = (HttpURLConnection) http.openConnection();
        System.out.println(http);
        openCon.setRequestMethod("GET");
        openCon.setDoOutput(true);
        openCon.setConnectTimeout(60 * 1000);
        openCon.setReadTimeout(60 * 1000);
        System.out.println("Well I got this far.");
        BufferedReader br = new BufferedReader(new InputStreamReader(openCon.getInputStream()));
        System.out.println("Can I get this far?");
        while ((inputLine = br.readLine()) != null) {
            System.out.println("What is cool? " + inputLine);
            return inputLine;
        }
        br.close();
        return null;
    } catch (IOException e1) {
        e1.printStackTrace();
        return "Error: " + e1;
    }
}

but for some reason I keep getting an error on right after the line that says "Well I go this far" I am unsure what I am doing wrong I have tried so many different things online but none of them seem to work. I should also mention that when I run it locally it works just fine.
