➜  ~ efetch -db nuccore -id AF086833 -format gb  > AF086833.gb

                 '_headers' => bless( {

                                                          'client-warning' => 'Client-Warning'
                                                        },
                                        'client-date' => 'Mon, 01 May 2017 05:34:27 GMT'

This problem can be fixed by either setting the PERL_LWP_SSL_CA_FILE
envirionment variable or by installing the Mozilla::CA module.

To disable verification of SSL peers set the PERL_LWP_SSL_VERIFY_HOSTNAME
envirionment variable to 0.  If you do this you can\'t be sure that you
communicate with the expected peer.
