Hello @GauravK ,

Are you running the tools behind a proxy server ? 

It may be Firewall or proxy issues, in this case make sure that the necessary ports and protocols are allowed and that the proxy settings are configured correctly.

Check the Network proxy settings and recommendation in the following User manual:

• UM1718 : STM32CubeMX User Manual 
• UM2609: STM32CubeIDE user guide

No proxy server. But firewalls can be there...

But I didnt face this issue previously... this week only observed

I tried changing network connections settings... but same issue faced
