Users experience a disconnect error when attempting to run a specific Power Automate flow from a SharePoint list.

Fixing the SharePoint Power Automate Flow Disconnect Error

Product: SharePoint and Power Automate
Device & OS: not provided
Scenario: Triggering a flow using the 'For a selected item' action from a SharePoint list.
Observed behavior: A message stating 'Sorry, there’s been a disconnect' appears, preventing certain users from running the flow despite having correct list permissions.

Before you start

Verify that the affected users have both the necessary SharePoint list access and the appropriate 'run-only' permissions configured within the specific Power Automate flow settings.

Solution 1Recommended

Verify Run-Only Permissions and Re-authenticate Connections

Use this solution to ensure that specific users have the correct flow execution rights and that the underlying service connections have not expired.

Even if users have permission to access a SharePoint list, they must also be explicitly granted permission to run the associated Power Automate flow. Additionally, the connections used by the flow (like SharePoint or Office 365 Users) may need to be refreshed if their authentication tokens have become disconnected.

Open Flow Details

Navigate to the Power Automate portal, go to 'My flows', and click on the name of the affected flow to open its details page.

Check Run-Only Users

Locate the 'Run only users' box in the bottom right of the details page. Click 'Edit' and ensure the affected users or their Microsoft 365 groups are listed.

Re-authenticate Connections

Under the 'Connections' section of the flow details, check for any alerts indicating a broken connection. If found, click the connection and select 'Fix connection' or 'Update' to re-enter your credentials.

Diagnostic Logging: If the issue persists, press F12 in your browser to open Developer Tools, trigger the flow, and check the Network tab for failed API calls to gather more diagnostic data.

Solution 2

Recreate the Flow Trigger

Use this solution if the flow is corrupted or stuck in a disconnected state for the 'For a selected item' action.

Frequently Asked Questions

Why does the 'For a selected item' trigger fail for only some users?

This typically occurs due to missing 'run-only' flow permissions for those specific users. Even if they have full access to the SharePoint list, they need distinct execution permissions granted within the Power Automate flow settings.

Does clearing the browser cache fix SharePoint flow disconnects?

While clearing cache and cookies can resolve basic session conflicts, deeper flow disconnect errors usually require re-authenticating the flow's connections in Power Automate or fixing the trigger configuration.

How do I check flow connection diagnostics?

You can press F12 to open your browser's Developer Tools. Go to the Network tab, attempt to trigger the flow from the SharePoint list, and look for failed API requests (usually 400 or 401 status codes) to identify where the authentication drops.
