smt-ncc-scc-migration fails with curl error 60

This document (7016024) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Subscription Management tool 2.0.x
SUSE Linux Enterprise Server 12
SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Server 10

Situation

While in the process of migrating SMT from Novell Customer Center to SUSE Customer Center, the smt-ncc-scc-migration command returns the following curl error:

Connection to registration server failed with: 500 CURL ERROR(60) Peer certificate cannot be authenticated with known CA certificates
Failed to get product information from SCC. Migration is not possible.

Resolution

Please make sure access to *suse.com is allowed by firewall rules. As updates are distributed via a 3rd party proxy system to provide a better download experience, it is not advisable to restrict access to IP addresses as the operator of the systems may change them any time without notice.

Cause

In this particular environment the connection was established via a proxy but failed later on without obvious reason in /var/log/smt/smt-ncc-scc-migration. It turned out access to the respective website was forbidden by firewall rules.

Additional Information

Shortened example for a failed migration:
