Steps to reproduce the behavior

1. Click on the red icon:

2. Select "Start server"

Expected vs actual behavior

I'd expect the server to start.

Logs

When I run the docker command myself I get the following:

Hi, a few questions to debug further.

What platform are you on? If Mac or windows is docker desktop running?

And also if windows are you running the docker commands in WSL? Because VSCode might not be.

Let me know, and hope some of the above helps.
