"Hmm... looks like this file doesn't have a preview we can show you" when previewing a document

Issue
When using the Preview pane within FYI, the preview of the file does not load and instead shows the following error with the option to download the file:

"Hmm... looks like this file doesn't have a preview we can show you"

Cause
This occurs when there is a disconnection of SharePoint and re-authentication of SharePoint is required.

Solution

1. Sign into SharePoint as prompted in the Preview pane.
2. Then refresh the screen and check that the Preview pane displays.

If you still have the issue, clear the local storage in your browser. The following shows the steps when using Chrome as your browser.

1. Close all open tabs in your browser.
2. Press F12 to open the Developer tools.
3. Display Applications (you may need to select this by clicking >>)
4. Click Storage.
5. Click Clear site data.
6. Log back into FYI.
7. Preview the document and confirm it loads as expected.
