postgresql odbc authentication error

Hi everyone:


I've been having trouble connecting to PostgreSQL by ODBC. The aplication responds with an error: "password authentication failed for user 'postgres'". I try this credentials with other clients and work fine.

I have installed npgsql-4.0.10 and configure system DSC in windows.

The server don't use SSL Encryption.


Thank you!

Hi @Anonymous , 

You could try to delete the credential in Datasource Setting, then re-enter it to see whether it work or not. You could try to refer to Connecting Power BI To PostgreSQL  for details.

Hi @Anonymous , do you have '%' in your password? If it's the case, you can try to replace '%' by '%25'
