I'm running a very simple spider that sends two POST requests. (code attached)
On my home computer it works just fine, but on scrapinghub I get the same error for each request sent:
[scrapy.core.scraper] Error downloading <POST https://baca.ii.uj.edu.pl/p12018/testerka_gwt/problems>: [<twisted.python.failure.Failure OpenSSL.SSL.Error: [('SSL routines', 'SSL23_GET_SERVER_HELLO', 'tlsv1 alert internal error')]>]
After that, the spider stops, there is no data collected.
I think it has to do with the site's certificate being outdated, but in the docs it says that Scrapy doesn't check that.
Try to replicate your environment when deploying the project to scrapinghub https://support.scrapinghub.com/support/solutions/articles/22000200400-deploying-python-dependencies-for-your-projects-in-scrapy-cloud
Sorry for late reply. Will try that, thank you.
