Docker Container Unhealthy

[kj21]

I'm trying to run paperless on macOS 10.15.5 Catalina on Docker. Had it working fine once but ran into consumption problems so I reinstalled.
Now, I've tried for some time to get the new containers up and running but get stuck with following docker error log message when I docker-compose up -d :

ERRORS: ?: (corsheaders.E013) Origin 'localhost:8080' in CORS_ORIGIN_WHITELIST is missing scheme or netloc HINT: Add a scheme (e.g. https://) or netloc (e.g. example.com).

I've checked the settings.py and docker-compose.yml files but it's all correctly schemed with http (also tried https), since there were multiple google entries stating that that might be the issue. I changed the ports in the settings file from 8080 to 8000 with no luck. To figure out if it's a docker problem, I ran a test container but with no problems, it was running fine. Has anybody run into the same error message and can tip me into the right direction? Thx
