Postgresql with nodered - Error: connect ECONNREFUSED 192.168.0.27:5432

[retegi]

Hi!
I am trying to connect PostgreSQL with nodered, but:
Error: connect ECONNREFUSED 192.168.0.27:5432

Nodered is inside a virtual machine (ip: 192.168.0.28)

PostgreSQL isinside virtual machine (192.168.0.27)
db_instalacion
user_instalacion
port:5432

Between the virtual machines the communication is correct, since I can ping without problem

What is happening?

Thanks

Have you etup PostgreSQL to allow Remote Connections?

Tons of info on the net e.g. "How To Configure PostgreSQL to Allow Remote Connections – TecAdmin" How To Configure PostgreSQL to Allow Remote Connections – TecAdmin

Also check (from the node-red machine) that port 5432 is open on the db machine. Using nmap for example.

Thanks! I have follow link steps. In the first time i had a problem because i couldn´t login in pgadmin after the pg_hba.conf file change. After i saw a comment thas says: use "host all all ::0/0 md5" and not "host all all :/0 md5" and the connection was ok! Thanks!
