Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it

Question

My steps:

Build image docker build . -t scrapy
Run a container docker run -it -p 8050:8050 --rm scrapy
In container run scrapy project: scrapy crawl foobar -o allobjects.json

This works locally, but on my production server I get error:

[scrapy.downloadermiddlewares.retry] DEBUG: Retrying https://www.example.com via http://localhost:8050/execute> (failed 1 times): Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it..

Note: I'm NOT using Docker Desktop, neither can I on this server.

What am I missing?

I already checked here:

UPDATE 1

I included EXPOSE 8050 in my Dockerfile, but get the same error. I tried netstat -a inside the docker container, but 8050 seems not to be in there?

C: oot\scrapy>netstat -a

UPDATE 3

In Windows Firewall I created new TCP port rule for both inbound and outbound allowing ports "80,443,8050" (for Domain/Private/Public)

Then retried running C: oot\scrapy>scrapy foobar -o allobjects.json in my container, but still get the "Connection was refused" error.

I ran these commands:

In my container: C: oot\scrapy>netstat -a
On my host OS: D:\Progams etstat -a

In neither output does port 8050 show up...but I had expected it to be there?

UPDATE 4

Based on @LSerni/@Pankaj's suggestions around Splash:

I don't know what I would need to enter instead of scrapinghub/splash in your example.

I tried: PS D:\Programs\image_addons> docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash

Unable to find image 'scrapinghub/splash:latest' locally
latest: Pulling from scrapinghub/splash
docker: image operating system "linux" cannot be used on this platform.

And:

PS D:\Programs\image_addons> docker run -p 8050:8050 -p 5023:5023 scrapy/splash

Unable to find image 'scrapy/splash:latest' locally
docker: Error response from daemon: pull access denied for scrapy/splash, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

Splash is installed via my Docker file into my scrapy image as can be seen from my post, so how would I need to start it?

UPDATE 5

Based on @Thiago Curvelo's comment around Splash:

So locally on Windows 10 and Docker desktop the above setup works for me where I'm not (at least not explicitly) starting a separate Splash instance, but perhaps that is logic build into Docker Desktop? On my server I can't use Docker Desktop as it does not support Hyper-V.
If you look at my Dockerfile, you see that I install scrapy-splash into my image.
Now to your point: apparently I need to start a Splash instance separately? Does that container have to run separately and in parallel from my scrapy container? Or could (and SHOULD?) I add the Splash image to my existing scrapy image and run a container based on that? I'm new to this so not exactly sure if that's what I should be Googling for.
(also I was just attempting scrapy/splash as I thought perhaps the scrapinghub part was referring to the image name, in my case scrapy, guess I was wrong about that too ;-))

You need to fire up a Splash instance first, and make it listen on the port 8050. Eg.:

docker run -dit -p 8050:8050 --name my_splash scrapinghub/splash

Then, set the splash URL to point to that running container:

settings.py:

SPLASH_URL = 'http://my_splash:8050/'

And finally, start the Scrapy container, linking it to the Splash one:

docker run -it --link my_splash --rm scrapy

That way you'll be able to send Scrapy's requests to Splash.

You say you checked out this question.

Did you start the Splash container? I quote from Pankaj's answer to the above question:

Run the splash on docker

# Start the container:
    $ sudo docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash
# Splash is now available at [...] ports 8050 (http) and 5023 (telnet).

Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it
