When I try to scrape a certain web site (with both, spider and shell), I get the following error:

Here is 100% working code.

What you need to do is you have to send request headers as well.

Also set ROBOTSTXT_OBEY = False in settings.py

# -*- coding: utf-8 -*-
import scrapy, logging
from scrapy.http.request import Request

class Test1SpiderSpider(scrapy.Spider):
    name = "test1_spider"

    def start_requests(self):

        headers = {
            "Host": "www.firmenabc.at",
            "Connection": "keep-alive",
            "Cache-Control": "max-age=0",
            "Upgrade-Insecure-Requests": "1",
            "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36",
            "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
            "DNT": "1",
            "Accept-Encoding": "gzip, deflate, sdch",
            "Accept-Language":"en-US,en;q=0.8"
        }

        yield Request(url= 'http://www.firmenabc.at/result.aspx?what=&where=Graz', callback=self.parse_detail_page, headers=headers)

    def parse_detail_page(self, response):
        logging.info(response.body)

EDIT:

You can see what headers to send by inspecting the URLs in Dev Tools
