Perhaps one of you knows how I can fix this problem.

Thank you very much and have peaceful holidays.

Can you still launch the CLI? If yes, post the output of pio system info here, then pio home.

If the CLI is not launchable, search your home folder (Windows: C:\Users\<user>\.platformio for penv\Scripts\pio.exe, then launch a regular terminal, and use the full path to pio.exe instead of pio for the previous commands.

Solution:
If you are working in an enterprise environment with a corporate SSL inspection proxy
(Zscaler, McAfee, etc.) and PIO Home hangs or shows a blank screen / HTTPClientError inside
VS Code, follow these steps:

  1. Disable strict SSL verification in PIO Core:
    Run this command in your terminal / PowerShell:
platformio settings set enable_proxy_strict_ssl false
  1. Set explicit Host & Port in VS Code settings.json:
    Add the following settings to your VS Code User settings.json:
"platformio-ide.pioHomeServerHttpHost": "localhost",
"platformio-ide.pioHomeServerHttpPort": 8008

  1. Add environment variables to bypass local loopback proxying:
    Add NO_PROXY=127.0.0.1,localhost,::1 and PLATFORMIO_NO_SSL_VERIFY=1 to your environment
    variables.

  2. Ensure manually extracted packages contain .piopm:
    If you manually downloaded/extracted packages (like contrib-piohome) to bypass proxy blocks
    in .platformio/packages/, ensure a .piopm file is present inside the package directory,
    otherwise PIO Core will endlessly attempt to re-download it via proxy.

After restarting VS Code, PIO Home loads cleanly inside the embedded VS Code tab!
