I wanted to try out the new STMCubeMX2 with one of the suitable STM32C5 MCU and I get this error

Not sure what does this mean, is there any certificate needed to use STMCubeMX2 ?

Hi @Srikar and Welcome to ST Community!

In this case, what you need is to configure a proxy or a certificate to be able to access the servers and download packages.

  • Get your certificate from your company IT or company portal.
  • Place it under C:\certificate, for example.
  • Add the Windows environment variable NODE_EXTRA_CA_CERTS with the path to this certificate file. (Make sure that the path has no quotes.)

  • Finally, restart STM32CubeMX2.

You can also refer to this article for more details on: How to configure the proxy or certificate
