Connection refused.

Hi everyone, I've just installed webratio and tried to connect the database. When refreshing database, I get an error containing 'org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.'. I have watched training videos and read documents on the webratio website.

More info:

ebratio version: 7.2.18

windows 10 64bit

postgresql9

 

Thank you

Hi,

first of all I suggest you to check your postgres installation and reinstall it if is required. When Postgres is working you can perform next steps (e.g. database connection).

In fact at this moment referring to your descriptions the issue does not depends on WebRatio.

I hope this will help you

Hi Alberto,

Thank you for the reply. Let me explain it more.

I installed Webratio 7.2.18 student version on my windows 10, and without any changes I created my empty database with the properties: URL localhost:5432, type postgres9 and my credential and also imported many jdbc drivers each time to check if it worked but all came to nothing. My java version is jdk 1.7.

Another thing might help to find the root cause is that when I install postgresql-9.4.26-1-windows-x64.exe I get another error:  'password authentication failed'

Thank you

Hi,

to help you please better describe us your case and the followed steps.

First of all you can verify the string connection to Postgres and test it with another dbms manager tool through the same jdbc driver used (imported) in WebRatio.

Please check the presence of any restriction due to firewall rules or network configuration (protocol, host, port and so on) or Postgres security settings.

Keep in mind that you have to use the correct version of the jdbc driver that must be compatible with the version of Postgres (e.g. 9.4.x) and java (e.g. Oracle jdk 1.7) in use. For more detail please refer to the official Postgres donload page with compatibility table: https://jdbc.postgresql.org/download.html.

Moreover please refer to this guide https://my.webratio.com/learn/learningobject/connecting-the-database-v-72.

Regards
