I'm inside a dashboard created using the Splunk Enterprise Dashboards Beta app, trying in the edit mode to add an icon by clicking a button that should show me a drilldown menu with various icon options. Unfortunately I got instead the following error message:
503 Service Unavailable
The same error is produced when I try to upload a background image from the Configuration section.
For a better understanding I inserted two screenshots depicting the mentioned problem.
Error 503-adding an icon
Error 503-adding a background image
It is important to notice that for the background image the image seems to be uploaded correctly by seeing the image resized but apart from the presence of the error immediately after the upload the image itself is not displayed in the dashboard.
Does anyone have any idea or something like that about it?
