ERROR: The certificate of ‘<server name>’ hasn't got a known issuer. 

Cause

Permissions are missing:

-rw-r-----. 1 root root 1639 Dec 6 2017 ca-cert-custom.pem 

should be 

-rw-r-xr-x. 1 root root 1639 Dec 6 2017 ca-cert-custom.pem 

Solution

In order to fix this, please run the following commands and try the wget command again:
 

# cd /etc/pki/ca-trust/source/anchors 

# chmod a+rx ca-cert-custom.pem
