Configure proxy settings for the on-premises data gateway
Your work environment might require that you go through a proxy to access the internet. This requirement could prevent the Microsoft on-premises data gateway from connecting to the service.
The following post on superuser.com discusses how you can try to determine if you have a proxy on your network: How do I know what proxy server I'm using? (SuperUser.com).
Although most gateway configuration settings can be changed by using the on-premises data gateway app, proxy information is configured within a .NET configuration file. The location and file names are different, depending on the gateway you're using.
There are three configuration files associated with using a proxy with the on-premises data gateway. The following two main configuration files apply to the gateway and its configuration process.
- The first file is for the configuration screens that actually configure the gateway. If you're having issues configuring the gateway, look at the following file: C:\Program Files\On-premises data gateway\enterprisegatewayconfigurator.exe.config. On the on-premises data gateway (personal mode), the corresponding file is %LocalAppData%\Microsoft\On-premises data gateway (personal mode)\PersonalGatewayConfigurator.exe.config.
- The second file is for the actual Windows service that interacts with the cloud service using the gateway. This file handles the requests: C:\Program Files\On-premises data gateway\Microsoft.PowerBI.EnterpriseGateway.exe.config. On the on-premises data gateway (personal mode), the corresponding file is %LocalAppData%\Microsoft\On-premises data gateway (personal mode)\Microsoft.PowerBI.DataMovement.PersonalGateway.exe.config.
If you're going to make changes to the proxy configuration, these files must be edited so that proxy configurations are exactly the same in both files.
The third configuration file will need to be edited for the gateway to connect to cloud data sources through a proxy.
- C:\Program Files\On-premises data gateway\m\Microsoft.Mashup.Container.NetFX45.exe.config
On the on-premises data gateway (personal mode), the corresponding file is %LocalAppData%\Microsoft\On-premises data gateway (personal mode)\m\Microsoft.Mashup.Container.NetFX45.exe.config.
The following section describes how to edit these files.
Configure proxy settings
The following sample shows the default proxy configuration found in both of the two main configuration files.
<system.net> <defaultProxy useDefaultCredentials="true" /> </system.net>
The default configuration works with Windows authentication. If your proxy uses another form of authentication, you must change the settings. If you aren't sure, contact your network administrator.
We don't recommend basic proxy authentication. Using basic proxy authentication might cause proxy authentication errors that result in the gateway not being properly configured. Use a stronger proxy authentication mechanism to resolve.
In addition to using default credentials, you can add a
<proxy> element to define proxy server settings in more detail. For example, you can specify that your on-premises data gateway should always use the proxy, even for local resources, by setting the bypassonlocal parameter to false. This setting can help in troubleshooting situations in order to track all HTTPS requests that originate from a gateway in the proxy log files. The following sample configuration specifies that all requests must go through a specific proxy with the IP address 192.168.1.10.
<system.net> <defaultProxy useDefaultCredentials="true"> <proxy autoDetect="false" proxyaddress="http://192.168.1.10:3128" bypassonlocal="false" usesystemdefault="true" /> </defaultProxy> </system.net>
You'll also need to edit the Microsoft.Mashup.Container.NetFX45.exe.config file if you want the gateway to connect to cloud data sources through a gateway.
In the file, expand the
<configurations> section to include the following contents, and update the
proxyaddress attribute with your proxy information. The following example routes all cloud requests through a specific proxy with the IP address 192.168.1.10.
<configuration> <system.net> <defaultProxy useDefaultCredentials="true" enabled="true"> <proxy proxyaddress="http://192.168.1.10:3128" bypassonlocal="true" /> </defaultProxy> </system.net> </configuration>
Configuring this third file might be necessary if your proxy is a requirement for all internet communication, especially for corporate usage where networks are secure and locked-down. If a proxy is required for gateway communication, it's likely also needed for any internet traffic from containers. In this case, the gateway might appear to be operating successfully until any container makes any external (internet) query. This issue is especially applicable to dataflows, which attempt to push the resulting query of on-premises data to Azure Data Lake Storage. But it also applies when a gateway query merges an on-premises dataset with an internet-bound dataset.

Change the gateway service account to a domain user
As explained earlier, when you configure the proxy settings to use default credentials, you might come across authentication issues with your proxy. This situation occurs when the default service account is the Service SID, and not an authenticated domain user. If the proxy on your organization requires a domain account in order to authenticate the request, you can change the service account of the gateway to a domain service account to allow the proper authentication with your proxy. For more information about how to change the gateway service account, go to Change the on-premises data gateway service account.
We recommend that you use a managed service account to avoid having to reset passwords. Learn how to create a managed service account within Active Directory.
