Hi,
Simplify3D is a slicer SW for 3D printing. I used it under 13.2 and needed the S3D-support to add the following link:

ln -s /var/lib/ca-certificates/ca-bundle.pem /etc/ssl/cert.pem

Comment from S3D-support: The SSL certificates in some versions of OpenSuse are not where Simplify3D expects them to be.

The same link is necessary for LEAP 15.
Cheers,
Knut
