SSL Error

See original GitHub issue

Description

I get an SSL error on a working website. The error is the following: <twisted.python.failure.Failure OpenSSL.SSL.Error: [('SSL routines', 'ssl3_read_bytes', 'sslv3 alert handshake failure')]>

Steps to Reproduce

Just execute

scrapy shell https://akut-international.com/

Expected behavior: HTML should return

Actual behavior: SSL Error

Reproduces how often: 100%

Scrapy       : 2.4.1
lxml         : 4.1.1.0
libxml2      : 2.9.7
cssselect    : 1.0.3

cryptography : 3.3.1

Additional context

I tried many additional verifications:

openssl s_client -connect akut-international.com:443 -servername akut-international.com -> returns a working handshake
I updated scrapy (see the version I used)
It work with requests.
I have the same issue with:

Scrapy       : 1.5.0
lxml         : 4.1.1.0
libxml2      : 2.9.7

Is that a not working combination? You can test on the website; you should come to the same conclusion as me

It solves my problem but you might to change some line here: https://github.com/scrapy/scrapy/blob/master/setup.py#L22

Not really, that should be the lowest Twisted version Scrapy supports, and it remains the same.

We could cover this issue somewhere in the documentation, but I’m hoping people will easily find this issue from now on, and that will serve as documentation enough.
