Can you help me to connect to Amazon RDS PostgreSQL Database from a VB.net Application. I already using a Npgsql .net data provider to connect to a local database.I am using the following connection string but getting a error message like
"Failed to establish a connection to
'ec2-dynanet-tomcat-new.cas1xn8fsgaw.ap-southeast-2.rds.amazonaws.com'."
conn = New NpgsqlConnection("Host=ec2-dynanet-tomcat-new.cas1xn8fsgaw.ap-southeast-2.rds.amazonaws.com;port=22;Username=xxx;Password=xxxx;Database=esurvey2")

Whenever I attempt to connect to my PostgreSQL database as a data source, I get the error message below.
Other users have recommended using an odbc connection? Why does an odbc connection work rather than a PostgreSQL connection for a PostgreSQL database in Power BI?
Had attempted to connect to my PostgreSQL database with all the correct credentials, failed with the error message mentioned. I had connected to the same database with an odbc connection perfectly.
I have a question, I do not know how to solve it yet. Perhaps someone here has faced a similar issue.
We have a PostgreSQL DB hosted on Gcloud. We usually use a cloud proxy to connect with the database. It usually works very well!! In a nutshell the proxy connect a port from local host, to the actual DB host.
However this time, we want to connect it with Microsoft SSMS. We have not find an option where we can connect Microsoft SSMS with a DB running locally (this means connecting to a database on a port in local host).
The ultimate goal is to connect the database with Power BI. So if someone know how to connect a PostgreSQL DB hosted in GCloud to power BI that would also be very helpful!!
We have followed this tutorial:
https://www.anibalum.com.ar/2020/06/creating-linked-server-with-postgres.html
However we get the following error:
The linked server has been created but failed a connection test. Do you want to keep the linked server?
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "PAPERFLOWDB".

I'm trying to connect from Oracle Database (dblink) to Postgresql database use Oracle Database Gateway (dg4msql 19), on the Oracle Database Gateway for MS SQL Server all work fine. On the Oracle DB create dblink, but when try to connect get Error message:
ORA-28500 Oracle ODBC SQL Server Wire Protocol driver Socket closed
08S01 Oracle ODBC SQL Server Wire protocol driver
The server does not support SSL {HY000} !
listener work, tnsnames.ora also give correct answer. May be in initdg4msql.ora file I have to use some string to connect without SSL?
HS_FDS_CONNECT_INFO = postgre_servet.net:5432//database - I don`t known that is correct for PostgreSQL, or for PostgreSQL should use only ODBC connection?
How correctly use HS_FDS_CONNECT_INFO = postgre_servet.net:5432//database, or for PostgreSQL should I use only ODBC connection?
The PostgreSQL server is not configured to accept SSL connections.
First, verify that PostgreSQL was built with SSL support: that can be seen from the output of pg_config --configure (should contain --with-openssl).
To configure SSL support, set ssl = on in postgresql.conf and provide a server certificate and private key (parameters ssl_vert_file and ssl_key_file). Reload PostgreSQL to activate.
For details, read the documentation.
I am trying to create a linked server between the warehouse and a amazon cloud service.
The service provide is using a PostgreSQL database.
I have installed the ODBC Driver (12.10) on my server but I keep getting this error.
I am not sure how to work around this as I have never used Postgres before.
I am trying to create a connection from AWS Glue to MongoDB, but when I test the connection it fails with error: "Check that your connection definition references your Mongo database with correct URL syntax, username, and password. Exiting with error code 30". I know that my connection parameters are correct because I can connect with the same host, port, database, user name, and password from another client application (DataGrip). And I know that my VPC configuration should be correct too because I have another connection in the Glue, to connect to the PostgreSQL database on-premise with public IP, that works just fine.
My MongoDB version is 4.4.1. I am out of ideas what else can cause the problem. Is anyone successfully connects to MongoDB form Glue and run the Crawler?
