I can't get it working

It says zero config, but for the life of me I can't get it working, lol..
Here's my Compose file:
version: '3'
services:
scope:
image: weaveworks/scope
container_name: scope
hostname: scope
network_mode: "host"
ports:
- "4040:4040/tcp"
pid: "host"
privileged: true
labels:
- "works.weave.role=system"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:rw"
command:
- "--probe.docker=true"
- "--weave=false"
When I run it, I can't get to the page; nothing but:
This site can’t be reached
and looking at my open ports on the machine, port 4040 isn't open.
Here's the log shown in Portainer once the container is up:

For the record, I added the --weave=false to my compose file because previously the logs showed a bunch of errors about it, and said "if you're not running weave.net you can add the flag", and I thought I had read on the website that weave.net isn't required, so I did that to mute the errors.
What's wrong?
I'm running the latest versions on Scope, as well as Docker Desktop on Win 10 x64.
I also have some questions:
- Does Scope NEED to be run in Host mode? Can it be run in Bridged mode instead?
- Can I change the port from 4040 to something else?
- When it's running, it doesn't show any published ports in Portainer?
- The log shows it running on 127.0.0.1, does tit need to be running on 0.0.0.0 instead?
Sorry for the newbie questions, but I am a Docker newbie, lol.
Thanks for any help!

When I run it, I can't get to the page; nothing but:
What URL did you use? On Windows you need to put the IP of the Docker VM in the browser.
Does Scope NEED to be run in Host mode? Can it be run in Bridged mode instead?
I think that is the same question as #3340. "Probably, with a little tweaking".
Can I change the port from 4040 to something else?
Yes. https://www.weave.works/docs/scope/latest/faq/#using-a-different-port
When it's running, it doesn't show any published ports in Portainer?
Since scope runs in the host network namespace, effectively all ports are published.
The log shows it running on 127.0.0.1, does tit need to be running on 0.0.0.0 instead?
It is.
<app> INFO: 2019/11/01 20:07:38.920779 listening on :4040
The references to 127.0.0.1 in the log are the probe talking to the app, and in the single-machine case that is fine.
I know this issue is for windows but if anyone has the same problem on Mac this may help you.
The trick is to remove network_mode: "host" which does not work on Mac docker/for-mac#1031
I also had to add the ports section "0.0.0.0:4040:4040", this enabled me to see weave in http://localhost:4040
Here is what works for me now
services:
scope:
image: weaveworks/scope:1.13.1
pid: "host"
privileged: true
labels:
- "works.weave.role=system"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:rw"
command:
- "--probe.docker=true"
ports:
- "0.0.0.0:4040:4040"
Sadly, if you follow the official documentation you will not be able to get it to work on Mac and go on a wild goose chase to fix it.
@jordotech please file a bug report noting what is wrong in the documentation.

It was brought up in 2017 and contributors were made aware:
#2842 (comment)
But I will make a new issue
OK, I'll reopen #2842, thanks.
@jordotech would you like to make a PR to update the docs?
@bboreham correct me if I'm wrong but these docs do not appear to be part of this repo? https://www.weave.works/docs/scope/latest/installing/#using-docker-compose
