Tools/CAD network addresses

[Andrei Chichak]

Good day,

I'm using CubeMX 6.15.0 and CubeIDE 1.19.0 on MacOS 15.6.1 on Intel and Windows 10.

I've got a little situation, when generating footprints for Altium, I go into <Tools><CAD> and after a short period CubeMX will say "Connection lost... Please check network status".

I try again and again, Windows, Mac, CubeIDE, CubeMX. Always the same result.

Then I connected my laptop to a hotspot on my phone that bypasses our firewall and - BAM - I get the footprints. Apparently one of the necessary IP addresses is being blocked, likely due to attacks form another IP in the same subnet band.

Question: So I can go to my networking guy and get the connection through, what IP bands are ST using when generating these CAD symbols?

Thanks,

Andrei

Hello @Andrei Chichak 

ST does not officially publish a list of IP addresses for their CAD services. However, you can whitelist by domain name

CubeMX typically connects to the following domains for CAD/footprint generation:

1-  www.st.com

2-  www.ultralibrarian.com (ST partners with Ultra Librarian for CAD models)

Thank you for your info.

The actual address was api.ultralibrarian.com, right domain, wrong IP range completely.

What we have subsequently noticed is that generating Altium Designer CAD Model zip files will trigger an error 500, but the pcad options work properly.
