Network connection issue in cube ide

[qw2]

Hi community,

I'm encountering a "network connection failed" error in my Cube IDE. Despite reinstalling the IDE multiple times, the issue persists. As a result, I'm unable to generate the code. Any suggestions on how to resolve this?

Hello @qw2 ,

First let me thank you for posting.

Before checking the connection, you should set the connection parameters for STM32CubeIDE:

Go to [Window]>[Preferences]>[General]>Network connections]

Change [Active provider] to Manual.

Update the proxy entries for HTTP and HTTPS with specific HOST, Port, User, and Password using the [Edit...] button.

Then, go to [Window]>[Preferences]>[STM32Cube]>[Firmware Updater] and click on the "Check connection" button.

For more details, check the STM32CubeIDE user manual UM2609 section 1.5.3 Preferences - Network proxy settings.

Thanks.

Mahmoud
