[ERROR] HTTP request failed: Get https://api.ssllabs.com/api/v2/info: x509: certificate signed by unknown authority (ref#2)
yum install -y ca-certificates.noarch
Same issue here on Linux - I have updated CentOS ca-certificates package to ca-certificates-2017.2.14-65.0.1.el6_9.noarch.rpm and it did not help. Also tried to manually put the DigiCert certs to /etc/pki/ca-trust/source/anchors/ and running update-ca-trust and still not working. Also curl https://api.ssllabs.com/api/v2/info does not work, but browser on my MacOS has no problem with this URL... This started happening since 4'th of May, before that it was working fine.
