We are trying to upload slides via API, but so far it hasn't worked.
We launched the distribution via `docker-compose -f caMicroscope.yml up -d`.
The `docker ps` command shows the following running containers:
```
376550a58ffa distro-back "docker-entrypoint.s..." 2 weeks ago Up 1 second 0.0.0.0:4010->4010/tcp ca-back

601fb4a33507 mongo:4.2-bionic "docker-entrypoint.s..." 2 weeks ago Up 2 seconds 27017/tcp ca-mongo
```
Next, based on the SlideLoader documentation (https://github.com/camicroscope/SlideLoader/tree/v3.12.0) we try to send a request to http://localhost:4000/upload/start, using a simple code, but we get an error.
Here is the code:
```
import requests
url = 'http://localhost:4000/upload/start'
x = requests.post(url)
print(x)
```
Error:
`Failed to establish a new connection: [Errno 61] Connection refused'`
What are we doing wrong?
Thanks
