### Description

I am trying to download a document from the link http://pravo.gov.ru/proxy/ips/?savertf=&link_id=0&nd=128284801&intelsearch=&firstDoc=1&page=all
Everything works fine in the browser, but when I try to automate this process through scrapy, everything break down.
### Steps to Reproduce

1.Create new spider `scrapy genspider test pravo.gov.ru`
2. Paste code
```
import scrapy


class TestSpider(scrapy.Spider):
    name = "test"
    allowed_domains = ["pravo.gov.ru"]
    start_urls = ["http://pravo.gov.ru/proxy/ips/"]

    def parse(self, response):
        yield scrapy.Request(
            self.start_urls[0] + f'?savertf=&link_id=0&nd=128284801&intelsearch=&firstDoc=1&page=all',
            callback=self.test_parse,
            encoding='cp1251') #The same behavior without this line
           

    def test_parse(self, response):
        pass
```

4. run
***OR***
run `scrapy fetch http://pravo.gov.ru/proxy/ips/?savertf=&link_id=0&nd=128284801&intelsearch=&firstDoc=1&page=all""`
**Expected behavior:** The document on the link is downloaded
**Actual behavior:** 
2023-04-28 00:07:35 [scrapy.core.scraper] ERROR: Error downloading <GET http://pravo.gov.ru/proxy/ips/?savertf=&link_id=0&nd=128284801&intelsearch=&fir
