Bypass IP / location lock of CloudFlare? #294

Closed minas90 closed 4 years ago

minas90 commented 4 years ago

Right now CloudFlare is active for the following website: https://censor.net.ua/ CloudScraper is working fine when I run it locally, but on ec2 instance in Frankfurt I'm getting error with message captcha.

When I do wget https://censor.net.ua locally I get ERROR 503: Service Temporarily Unavailable. On the ec2 instance I get ERROR 403: Forbidden.

My guess is that CloudFlare is blocking requests from certain locations or IP addresses, maybe when it's configured like that by the website owner. Any ideas how to fix that?

@minas90 hey.

My guess is that CloudFlare is blocking requests from certain locations or IP addresses

I think this is a correct guess, given that it works on your local machine and you get 503 using wget. Probably your instance' IP address got blacklisted. I don't think there is a way to fix. Try rotating IP address.

Thanks for quick response! I created a new ec2 instance and now I'm getting 503 with wget. The weird thing is that now I'm getting another error from CloudScraper: 404 - "body of 404 from the website"

This is the exact resource URL I'm trying to get: https://censor.net.ua/includes/news_uk.xml

Any ideas how it can happen?

@minas90 I quickly looked into this, and it seems that if you do pure curl|wget without any headers, cloudflare responds with 503. But indeed, i get 404 for cloudscraper calls 🤔 I think that it might be related to incorrect headers or maybe referrer?

codemanki commented 4 years ago

Oh, i think i see what is happening. Censor returns this in headers:

        href: 'https://m.censor.net.ua/includes/news_uk.xml',
        ntick: true,
        response: [Circular],
        originalHost: 'm.censor.net.ua',

I think they detect UA as mobile browser and redirect you to their m. subdomain for some reason

@minas90 try running this code

cloudscraper('https://censor.net.ua/includes/news_uk.xml', {headers: {
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'
}}).then((htmlStr) => {
  console.log(htmlStr)
}).catch((err) => {
  console.log(err)
})

It worked, thanks a lot! So strange that locally it works without the user-agent.
