With powerbi desktop I can easily connect with postgres database on server(192.168.1.5:32100) running on a port and a database_name. But doing the same with PowerBI on premise gateway I could not connect when adding a data source on gateway setting(gateway cluster). Below screenshot for reference. The first picture is of PowerBI desktop and the second one is on gateway settings. Is it something with the port?If yes I was able to connect on PowerBI desktop, if no then is there any way or am I missing something. Thanks in advance for the help.
Method 1
Install the Npgsql provider on the server that's hosting the data gateway (https://www.nuget.org/packages/Npgsql/4.0.2)
Reboot the server
Method 2
Connecting to PostgreSQL database using ODBC Connector
Using the below link download the latest version of ODBC connection for PostgreSQL database and Install
https://www.postgresql.org/ftp/odbc/versions/msi/
After installation completed, open the Power BI Desktop and choose Get Data
Instead of selecting postgresql database, this time we will choose ODBC. Select ODBC and click on Connect
A window will open and select “None” as Datasource Name (DSN)
In the same window, we have connection string. Here we have to provide proper connection details to connect postgresql database. We won’t be able to click “OK” until we have provided the correct connection string.
To get the proper connection string use this link.
https://www.connectionstrings.com/postgresql-odbc-driver-psqlodbc/
We have given the below connection string and able to click on “OK”
Connection String:
Driver={PostgreSQL ANSI(x64)}; Server=localhost; Port=6433; Database=foodmart
Enter the credentials and select the tables
Create a report and publish in Power BI service
Login to Power BI service and open settings of a report dataset
Expand gateway connection and now we can see that gateway is enabled and it is connected local gateway
Expand the data source credentials and enter the database credentials
Now go to datasets and click on refresh icon of the dataset
Dataset will get refreshed using the gateway
Should now be able to use the PostgreSQL data source type when creating the data source in Power BI Service.
Thanks,

Tried to deploy paginated report to Power BI service. But could not find a way to configure the database connection string under Pro license
Unfortunately this can't be changed in the portal after deployment. So either update and redeploy the RDL or update it using the API Reports - Update Datasources In Group.
I have developed Power Bi report using OData Source and deployed in power bi service. Need to do schedule refresh for the report. For that created and configure the connection to OData in Power BI Service to make the report Dataset refresh through the gateway followed the following the steps below:Clicked on Settings button in Power BI ans and selected "Manage gateways" option.
'Added data source to use the gateway' link
Specified all the parameters for Datasource settings
selected the configured gateway and data source from the list.
After the report Dataset is connected to OData via gateway. Refreshed the report Dataset to check for refresh status. I noticed the following errorUnable to find Data source one of the Gateway .Please help me out if I missing anything.
In my PowerBI desktop, I created a Jira dashboard report, and it works perfectly. On the Power BI desktop report, I can view all of my requested data.
Now, when I publish the report https://app.powerbi.com/ the report gets published successfully, however, when I am trying to schedule the refresh, I keep getting below error.
Failed to update data source credentials: The credentials provided for the Web source are invalid. (Source at https://jira.tools.com/.)
When I try to connect straight to my Jira, I know my credentials are accurate and working properly, and the same is true in Powerbi Desktop.
What could be the reason?
Your Jira server might be inside the firewall/inside a private network.
So, the first thing I suggest to try is setting up a Power BI Gateway. Then configure your Power BI Service refresh via that Gateway.
Useful links:
https://learn.microsoft.com/en-us/data-integration/gateway/service-gateway-install
https://learn.microsoft.com/en-us/power-bi/connect-data/service-gateway-data-sources
You'll want to do that on a Server inside your firewall & ensure Proxy settings are correctly setup - to access Internet.
If that doesn't do it - it's probably a more subtle cause (anywhere from the network configuration to how Active Directory is tied to Jira). Let us know, we'll take it from there.
Just installed Power BI Data Gateway on one of the companies servers.
The processes was smooth and very easy, I have assigned a name to the Data Gateway.
As it is linked to my email (I think this is going to be another problem when other employees trying to publish their reports), when I tried to configure datasource in my Gateway I get this error !

PBIGateway: The on-premises data gateway's service account failed to impersonate the user.
I am sure that my user ID and password are both correct, not sure why it is not working!!
This one had me stumped for days. Why would the PBI desktop app allow connections, seamlessly on your desktop and yet when you publish a report to the web, bong-bong no authentication, no credentials, nothing! It was very frustrating, and no specific details other than a plethora of connection IDs which mean nothing.
In the end, we found the problem was between how we've set up the Power BI Gateway on-prem, and whether the gateway service account on the gateway had the permissions to access our data sources, both from SQL Server on-prem and an Excel table in Sharepoint.
When setting up your Gateway (not a personal GW, but a server side one), we've created the gateway using the Admin local account. That was our first mistake. We couldn't connect to any of our SQL Server databases, from Sharepoint. So we've re-installed it using an Admin O365 AD account. Our SQL Server access was ok, but anything in Sharepoint wouldn't work - even though the same account was used to put Excel files and CSV files into Sharepoint.
We then noticed that the gateway was defaulted to a service account under the NT Authority group. Again, another local account. Changed that to another O365 account, but again - nothing would allow us to connect to the Excel sharepoint file! How hard can this be, when the Excel file connected fine inside PowerBI desktop! It was very frustrating.
So we've re-installed the on-prem gateway again, but this time used one AD account for it's sign on, and another system AD account for it's service account. We also publish the PBI report to the cloud, but the dataset would be failing to connect to the Excel file in Sharepoint. WHY!!!???
It came to that User tab and putting our on-prem gateway service account in the User list of the connector to the Sharepoint file.
VOILA!! It worked.
In summary:
Create your PBI reports in desktop and point everything you need to what ever you need in the Get Data wizards
If you're referring to an Excel file, DO NOT point to a local / network Excel file. You're wasting your time.
Put the Excel/CSV or whatever in sharepoint in a Documents folder somewhere
Click Manage Permissions on the file and add the On-Prem service gateway to the list
Next, open the Excel file on the web
And go ahead and open it in your local desktop Excel as well
Go to FILE --> INFO
Click Copy Location to store the location of the file in the clipboard. Save this string in notepad
Close Excel on-prem
Close Excel online
Go to your PBI report and edit the M-Code via the Advanced Editor of your data source
Replace the C drive location of your Excel filepath with the one copied into your notepad
Now your query is pointing to the Excel file in sharepoint.
Publish your report
Go to app.powerbi.com and go to your report's dataset
Click the three dots and go to Settings
Go to Gateway Cluster and lick Manage Gateway link
Open up your gateway cluster and go to your Excel data connector
Select it and click the Users tab
Add your on-prem gateway service account again to this list
Save
Refresh your dataset
Voila! No more errors.
I hope this lengthy answer has been enough for your to realise [1] microsoft write great software, but crappy user-experience with it and [2] you need to pass on the credentials of the gateway to any datasource that uses it, in reference to any datasource that require a gateway between on-prem and cloud reports.
We have same problem in powerbi gateway. Turns out the database password is expired. After reset password. Problem solved.
I have a problem when i want to use DirectQuery. I have a DomainController with installed SQL Server. I have installed Data Gateway and must modify the Service Account to Local System to be able to finish setup. i have setup the Data Gateway successfully in Enterprise Mode. In PowerBi.com everything looks fine and can see the Gateway and no errors.
When i now create a new File with a SQL connection and Mode "Import" and publish it to PowerBi.com, then it works fine and when i schedule a refresh, this works fine, too.
But i want to use DirectQuery on a Database table for example. For this scenario i have created a new Power BI File and selected the same database which i already created as DataSet in PowerBI.com under my Gateway. Then i load the data in the file and while trying to load it i am always receiving the following error message:
Create Connections
Alternate credentials for Windows authentication is
not supported in DirectQuery mode. Use your current windows
credentials, supply a database credential or switch to import mode.
In PowerBI.com under Gateways and Data source i have used Windows Authentication and used the Administrator account which has also permission on the Database. I dont know what this message means and i should change. Can someone help me?
it seems that your have a credential problem, I suggest you to go to File->Options and settings->Data source settings, then edit your data source [Edit Permissions...] and specify a valid Windows credential or database credential. After that, click "Refresh" button in the PBIX file.
Hope that helps!
If you cannot open the PBIX file, restart Power BI designer with an empty one and then go to the File, Options as explained above. You will find out that an "alternate" credential has been stored for your data source. Use your current credentials instead. Now, try to open the original PBIX file and it you will see that now Direct Query mode works.
