Cant open https web using Slimerjs, casperjs, phantomjs - automation

Question

This is first time i cant open website using headless browser such: phantomjs, slimerjs or casperjs. I just want to open website. I just create very basic script to open the website and take screenshot. but 3 (three) of them give me blank picture.
i try using:
--debug=true
--ssl-protocol=TLSv1.2 (i try each of available protocol)
--ignore-ssl-errors=true
Here my script:
Slimerjs
var page = require("webpage").create();
page.open("https://domain/")
.then(function(status){
if (status == "success") {
page.viewportSize = { width:1024, height:768 };
page.render('screenshot.png');
}
else {
console.log("Sorry, the page is not loaded");
}
page.close();
phantom.exit();
});
phantomjs
var page = require('webpage').create();
page.open('https://domain/', function() {
page.render('screenshot.png');
phantom.exit();
});
casperjs
var casper = require('casper').create({
viewportSize: {width: 950, height: 950}
});
casper.start('https://domain/', function() {
this.capture('screenshot.png');
});
casper.run();
I even try to use screen capture service to know if they can open or not. But all of them give me nothing too.
is there i miss something?

Answer 1

The issue is not because of PhantomJS as such. The site you are checking is protected by a F5 network protection
https://devcentral.f5.com/articles/these-are-not-the-scrapes-youre-looking-for-session-anomalies
So its not that the page doesn't load. It is that the protection mechanism detects that PhantomJS is a bot based on checks they have implemented
The easiest of fixes is to use Chrome instead of PhantomJS. Else it means a decent amount of investigation time

I will update this post with more details that I find. But my experience says, go with what works instead of wasting time on such sites which don't work under PhantomJS
Update-1
I have tried to import the browser cookies to PhantomJS and it still won't work. Which means there is some hard checks

I experienced this issue with phantomJS and the following service args resolved it:
--ignore-ssl-errors=true
--ssl-protocol=any
--web-security=false
--proxy-type=None
Can't help you with casperJS and slimerJS, and don't know exactly why this worked.
