Strange difference between `pio home` and automatic start via `platformio` command with code-server in Docker

[pandel]

Hi!

I am currently running the latest release of PlatformIO under Docker.

• code-server is reverse proxied via an SSL-secured NGINX proxy forwarded on port 8443
• PlatformIO is configured to use 127.0.0.1 with port 8008.

I noticed some strange behaviour:

• I am able to open the PlatformIO home page if i start pio home in a code-server terminal via https://docker.home.server:8443/proxy/8008/
• I am not able to open it if code-server automatically starts PlatformIO process via /config/.platformio/penv/bin/python -m platformio -c vscode home --port 8008 --host 127.0.0.1 --session-id 73169f810b382f2316f52618e2d777b4b6efbfda --shutdown-timeout 3600 --no-open -> Resulting error message in browser window: Protected PlatformIO Home session

Why is that? What is pio home doing differently here?

I attach my main configuration files for reference:

compose.yaml

  code-server:

    depends_on:

    restart: unless-stopped

nginx.conf
