Cypress not connecting to localhost - docker

Question

I have a docker compose file that holds my cypress container:
version: '3'

image: redis

For some reason when I start my server and then start cypress using docker-compose up --exit-code-from cypress I get the following error, that I cannot seem to debug, please note my server is running, and all are on the same network main
Cypress could not verify that this server is running:
> http://web:8000
We are verifying this server because it has been configured as your `baseUrl`.
Cypress automatically waits until your server is accessible before running tests.
We will try connecting to it 3 more times...

CypressError: cy.visit() failed trying to load:
http://127.0.0.1:8000/test/
We attempted to make an http request to this URL but the request failed without a response.
We received this error at the network level:
> Error: connect ECONNREFUSED 127.0.0.1:8000
Common situations why this would fail:
- you don't have internet access
- you forgot to run / boot your web server
- your web server isn't accessible
- you have weird network configuration settings on your computer
The stack trace for this error is:
