Error in Cloudforms certificate validation

Issue

• While configuring CloudForms workers SSL certificate validation error is seen in fog.log as below:

[----] E, [2017-09-04T14:21:47.347741 #15067:395134] ERROR -- : excon.error     #<Excon::Error::Certificate: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError) Unable to verify certificate. This may be an issue with the remote host or with Excon. Excon has certificates bundled, but these can be customized:

            `Excon.defaults[:ssl_ca_path] = path_to_certs`
            `ENV['SSL_CERT_DIR'] = path_to_certs`
            `Excon.defaults[:ssl_ca_file] = path_to_file`
            `ENV['SSL_CERT_FILE'] = path_to_file'
            `Excon.defaults[:ssl_verify_callback] = callback`
                (see OpenSSL::SSL::SSLContext#verify_callback)
or:
            `Excon.defaults[:ssl_verify_peer] = false` (less secure).

How to disable this check?
