For clarification, please note that I have found several similar questions on stackoverflow, but I could not fix my issue.
psql: could not connect to server: Connection refused” Error when connecting to remote database
psql: How to Allow Remote Access to PostgreSQL database
I am trying to connect to a postgres DB installed in a remote server. To create a connection from the client I am using QGIS plugin (Add PostGIS Layer):
The error that occurs is:
could not connect to server: Connection refused (0x0000274D/10061) is the server running on host "localhost" (::1) and accepting TCP/IP connection on port 5432
Additionally I added the host's IP Adress in the Host field, but then another error message occurs:
could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "hosts_ip_adress" and accepting TCP/IP connections on port 5432?
My settings are:
- Postgres installed version is 10.0 with PostGIS extension
- Host operating System: Windows 7
- Client operating System: Windows 7
I edited pg_hba.conf to:
host all all 0.0.0.0/0 md5
and changes listen parameter in 'postgresql.conf' to:
listen_addresses = '*'
both files are located in C:\Program Files\PostgreSQL\10\data
- restartet pgAdmin4
My devices are in the same network. Each one is connected via LAN cable. I suppose that a firewall is preventing the connection?
