Issue
One of my Player stopped displaying the updated content. IT is always displaying the background image. It was working fine before and now in CMS it was showing with a message like
" display is out of date but has not yet checked in with the server".
We uninstalled the Xibo Player, restarted and reinstalled it and when we click on connect in the Xibo player options it says " Bad Request"
