SSL Error while building Python from sources

And after some time I recieve:

I’ve never seen this before and there’s nothing similar over the internet.
Could it be a specific Jetson problem?

Hi,

SSLV3_ALERT_CERTIFICATE_EXPIRED error looks independent to the Jetson environment.
Have you checked this with the python developer?

Thanks.
