I am trying to install the PlatformIO IDE extension on a code-server v3.0.1 instance hosted in a docker container. I am running Docker Desktop on Windows 10 Pro and accessing code-server using Chrome 80. The extension seems to install fine using the extension manager in code-server, but when I try to open the PlatformIO Home tab, Chrome reports that 127.0.0.1:8010 did not send any data and therefore the PlatformIO Home page is not shown:

I am using the following Dockerfile:

FROM codercom/code-server:3.0.1

USER root

RUN apt-get update && apt-get install -y python3 python3-distutils \
	&& rm -rf /var/lib/apt/lists/*

USER coder

EXPOSE 8010

ENTRYPOINT ["dumb-init", "fixuid", "-q", "/usr/local/bin/code-server", "--host", "0.0.0.0", "--auth", "none", "."]

And the following docker-compose.yml:

version: '3.3'
services:
    code-server-platformio:
        image: r0zzy5/code-server-platformio
        ports:
            - '8080:8080'
            - '8010:8010'
        volumes:
            - './src:/home/coder/project'
