The server itself must be told to allow remote connections.
You might check these two things.
1. You can edit the postgresql.conf file (not sure where that is on your
system).
https://www.postgresql.org/docs/9.2/static/runtime-config-connection.html
Uncomment or add the line listen_addresses='*'. You can
tailor that to be more specific, but try this first.
2. The file pg_hba.conf also controls access. Look at this:
https://www.postgresql.org/docs/9.3/static/auth-pg-hba-conf.html
Be sure to restart the server after you make changes to these files.
Hope this helps,
