Failed connect to localhost:7474; Connection refused. Where is the neo4j-server.properties file?

I am trying to start my graph from Rstudio on Mac OSx, installed RNeo4j via devtools on (for R version 3.1.2) "startGraph("http://localhost:7474/db/data/")" and i received the following error:

"Error in function (type, msg, asError = TRUE) : Failed connect to localhost:7474; Connection refused"

It looks like it is an Error code: ERR_CONNECTION_REFUSED searching online, they recommend to modify conf/neo4j-server.properties file. But cannot seem to find the file to correct it.

Try connecting to bolt://127.0.0.1:7687 or See the log in $NEO4J_HOME/logs/neo4j.log file. There should be some error showing the exact ip neo4j has hosted to.

check conf/neo4j.conf, there is one line:

# With default configuration Neo4j only accepts local connections.
# To accept non-local connections, uncomment this line:
dbms.connectors.default_listen_address=0.0.0.0

For me I had changed the name of my local IP address from localhost to localhost.dev

To see your settings:

cat /etc/hosts

My one looks like this 

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost.dev
127.0.0.1   api.localhost.dev

In case you prefer to connect to neo4j without authentication, it is easy to change the default. The corresponding documentation for version 2.2.1 is here

Make the following change in the file conf/neo4j-server.properties file:

# dbms.security.auth_enabled=true
# 
dbms.security.auth_enabled=false

Are you using Neo4j 2.2? If so, you might need to specify the username and password (which you can set by going to localhost:7474 in your browser if you haven't already).
