Hello ST team,

I’m experiencing a persistent issue with STM32CubeMX (and STM32CubeIDE when using the integrated CubeMX). Whenever I try to create a new project or refresh MCU data, I get the following errors:

  • “Error downloading the following files: crdb.zip (Problem during download)”

  • “Download has failed, some data may not be updated. Please retry later.”

Other update functions (like firmware package updates) still work fine, so the internet connection is not the problem.
