Error Message: Negotiate Unknown

[ghost]

Hi, first of all thanks for your work :)

Since this morning I have a problem with websockets, i get this message:

Error Message: Negotiate Unknown Exception: undefined Error Data: 503

I know it has something to do with cloudfare but cloudscraper is used.

Do you have any idea?

I'm experiencing the same thing and it's definitely CloudFlare. It helped when I added a different referrer and user agent as a third argument into the cloudscraper function. I forked the code and tried different referrers. Using Microsoft Edge as the agent worked for me last night but Chrome and Firefox both did not.

{'Referer': 'https://www.google.ca', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36 Edge/14.14393'});

This is a hit or miss solution.

I hope to find a more permanent solution soon.

in the file : node.bittrex.api.js line ~215 function cloudscraper.get('https://bittrex.com/', callback of ~100 lines, {'Referer': 'https://www.google.ca', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36 Edge/14.14393', 'cookie': '__cfduid=check_browser_console; cf_clearance=check_browser_console'}

);

return wsclient;

};

Ok i put cookie yesterday but now it doesn't work anymore See posts below for the solution.

It will help a lot of others out if they can pass this argument in from the official package. If that user agent fails, you can pick and choose from a bunch here : https://developers.whatismybrowser.com/

When I added the standart browser headers like Accept-Encoding, Accept-Language etc, it worked.

{ 'Referer': 'https://www.google.fr', 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/603.3.8 (KHTML, like Gecko)', 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8', 'Accept-Encoding': 'gzip, deflate, br', 'Accept-Language': 'fr-FR,en-US;q=0.9,en;q=0.8', 'Cache-Control': 'no-cache', 'Upgrade-Insecure-Requests': 1, 'Pragma':'no-cache', }

We should be able to pass those extra headers via .options() so that it gets passed to the cloudscraper's third argument.
