Scrapy twisted connection lost in non-clean fashion. No proxy. Already tried headers

I am trying to crawl this site

https://www5.apply2jobs.com/jupitermed/ProfExt/index.cfm?fuseaction=mExternal.searchJobs

with scrapy and keep getting twisted request/disconnection errors. I am not using a proxy and I tried both setting the user agent and actually setting all the headers based on this answer

here is the code generating the request

def start_requests(self):
    url = 'https://www5.apply2jobs.com/jupitermed/ProfExt/index.cfm?fuseaction=mExternal.searchJobs'

    headers = {
        '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': 'en-US,en;q=0.8',
        'Connection': 'keep-alive',
        'DNT': '1',
        'Host': 'www5.apply2jobs.com',
        'Referer': 'https://www5.apply2jobs.com/jupitermed/ProfExt/index.cfm?fuseaction=mExternal.showJob&RID=2524&CurrentPage=2',
        'Upgrade-Insecure-Requests': '1',
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36'
    }

    yield Request(url=url, headers=headers, callback=self.parse)

and this is my traceback:

So thanks to discussion on github as well as in the comments to my question, it looks like the best course of action is to use a virtualenv with cryptography<2

credit to @paultrmbrth for helping so much

I tried compiling OpenSSL 1.1.0f with enable-weak-ssl-ciphers to build a static wheel, but I didn't manage to have it support TLS_RSA_WITH_RC4_128_MD5 (as ssllabs.com reports) for some reason. I'm laking OpenSSL building knowledge apparently. So the only option I see is to use a virtualenv with 'cryptography<2' for scraping that website.
