Applies to Product - Dynamics 365 Business Central
What’s happening?
The drag and drop functionality in Dynamics 365 Business Central is intermittently failing for users. Users report that while some files upload successfully, others get stuck on the "Working on it" message and eventually time out. This occurs both in office and home environments, affecting users on different operating systems (Windows 10 and Windows 11) and browsers (Edge and Chrome).
Potential Reason:
The underlying cause of this may be related to network setup problems, such as firewall settings, antivirus software, or custom DNS configurations. Internal telemetry indicates that the upload requests are unusually slow and not transferring data efficiently, despite the small size of the files being uploaded.
Troubleshooting:
- Test file uploads on different networks, including non-work networks like a mobile hotspot, to determine if this is network-related.
- Gather network traces and console logs to analyze the performance during the drag and drop process. Follow these steps:
- Close all browser windows.
- Open a new empty browser window.
- Open the development tools (usually by pressing F12).
- Click on the network tab and ensure recording is started (the recording button should be red) and "Preserve log" is checked.
- Navigate to the Business Central URL.
- When an error occurs or the page becomes unresponsive, click the "Export to HAR" button to save the file locally.
- Navigate to the console tab, right-click on any message, and choose "Save As" to save the log file locally.
- Send the HAR file and log file to the support team for further investigation.
