How to solve 504 HTTP Code in Scrapy-Splash - docker

Question

I use scrapy for a long time but now I need to use scrapy-splash for some reason.
I ran
docker run -it -p 8050:8050 --rm --name spider -v /etc/splash/proxy-profiles:/etc/splash/proxy-profiles scrapinghub/splash --max-timeout 3600
In /etc/splash/proxy-profiles/default.ini I write corporate proxy
Log:
[user#vir ~]$ sudo docker run -it -p 8050:8050 --rm --name spider -v /etc/splash/proxy-profiles:/etc/splash/proxy-profiles scrapinghub/splash --max-timeout 3600

To find out my docker ip: ip addr show docker0 | grep -Po 'inet \K[\d.]+'
It is 172.17.0.1
I try
curl 'http://172.17.0.1:8050/render.html?url=https://www.google.com/' --noproxy "*"
This --noproxy "*" is due to a company works behind a proxy.
And I get the 200 response in Docker Log. It says that proxy I set in /etc/splash/proxy-profiles/default.ini works correct.

Great! That's what I wanted
But when I try to implement ScrapyRequest and run Scrapy with code below
yield SplashRequest(
args={
'wait': 0.5,
'timeout': 10,
'proxy': '<hidden for security reasons>',
},
splash_url="http://172.17.0.1:8050",
url="http://www.google.ru/",
endpoint='render.html',
method="GET",
callback=self.parse_splash,
headers=headers,
dont_filter=True,
)
I got error

Important note!
When I use just requests - it works!
When I use Scrapy requests - it works!
When I use ScrapySplash requests - it doesnt work!
