It looks like it's an issue with your "Cisco Umbraco Cloud Security" product doing something strange with the certificates.

This is what my Google Chrome currently shows for the SSL certificate ( which is managed by GitHub, not by us )

Can you raise a support ticket with whoever manages your laptop security or directly with Cisco if you installed it?
