Account login issues caused by STM32CubeIDE 1.19.0

ZnMnCr · ‎2025-10-18

When I try to log in to my account, the software prompts "Connection lost"

After I rolled back the version to 1.17, this issue disappeared. Many users in the China region have encountered this problem, and it’s unclear if it exists elsewhere.

Hello @ZnMnCr

Let's try clearing any cached authentication data by deleting the .stm32cubemx and .stm32cubeide folders in your user directory, as corrupted cache files can lead to persistent login problems. Additionally, review your network and proxy settings within the IDE to ensure there are no hidden connectivity issues, and consider running the IDE as an administrator to rule out any permission-related problems.

Please try those steps and give me your feedback.
