What happened:
[master1] Completed phase in 0.00s
ERROR: Excon::Error::Certificate : SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate) (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
