Error 'Your administrator has blocked access to this client' in Data Loader

Publiceringsdatum: Jul 3, 2026
Beskrivning

A user's ability to connect to their Salesforce organization using Data Loader can be controlled by the Data Loader Partner and Data Loader Bulk Connected App settings. A Connected App is a framework that enables external applications, such as Data Loader, to securely integrate with Salesforce using APIs and OAuth.

By default, these Connected Apps allow individual users to self-authorize and connect with Data Loader without any additional configuration. If a System Administrator changes the Permitted Users setting to Admin approved users are pre-authorized, only users who have been granted access through their Profile or a Permission Set can connect to the organization using Data Loader.

        Note: This restriction applies to System Administrators as well as all other user types.

Users who encounter this Connected App restriction when logging in through Data Loader receive the following error:

   Sorry, your administrator has blocked access to this client.

Lösning

End users who encounter this error should contact their Salesforce organization's System Administrator for assistance.

To resolve the "Your administrator has blocked access to this client" error in Data Loader, a System Administrator must either revert the Connected App permissions to allow all users to self-authorize or explicitly grant access to specific users through their Profile or a Permission Set.

Option 1: Revert Connected App Settings to Allow All Users

If the Connected App restriction was configured unintentionally, reverting the setting to allow all users to self-authorize will restore Data Loader access for all users.

  1. Navigate to Setup and enter Connected Apps in the Quick Find box.
  2. Depending on your Salesforce experience:
    • In Lightning Experience, click Manage Connected Apps.
    • In Salesforce Classic, click Connected Apps.
  3. Select the appropriate Connected App (for example, Data Loader Partner or Data Loader Bulk).
  4. Click Edit.
  5. Under OAuth Policies, change the Permitted Users setting to All users may self-authorize.
  6. Click Save.

Option 2: Assign the Connected App via Profile or Permission Set

If access should be limited to specific users, assign the Connected App through the user's Profile or a Permission Set.

To assign the Connected App through a Profile:

  1. Navigate to Setup and enter Profiles in the Quick Find box.
  2. Click Profiles.
  3. Select the appropriate profile (for example, System Administrator or Standard User).
  4. Click Assigned Connected Apps.
  5. Click Edit.
  6. Under Installed Connected Apps, select the appropriate Connected App (for example, Data Loader Partner or Data Loader Bulk) and click Add.
  7. Click Save.

To assign the Connected App through a Permission Set, follow the same process after creating the appropriate Permission Set.
