Adding local catalog fails?

Hi,
I’am trying to add a local catalog but it fails with:

fatal: unable to access ‘https:///lab/rancher-compose.git/’: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
time=“2016-03-24T07:20:12Z” level=error msg=“Failed to clone the catalog from git err: exit status 128”

I have added my CA to /etc/ssl/certs/ca-certificates.crt

Regards
Christian
