Downloading Exports

[madukan]

Hi, I just got started with Plane.so. Fantastic concept, and well executed. Just a bit of playing around and was trying to download an export of the projects through the workspace:
Workspace > Settings > CSV Export
Seem to create the file, however upon clicking I get ERR_CONNECTION_REFUSED in Chrome browser. No download/zip comes through.
Any idea what might be going wrong? I am using Docker-compose with all local data/setup on a Macbook. So far everything else seem to work fine.
