With 3.0.x to enabled remote clients to connect to a HTTPS enabled browser the following parameters in the $NEO4J_HOME/conf/neo4j.conf need to be changed from the default of
#dbms.connector.https.address=localhost:7473
to
dbms.connector.https.address=0.0.0.0:7473
The change from localhost:7473 to 0.0.0.0:7473 will allow for remote connections to https://<Neo4j_Host_IP>:7473
