We run Xibo 2.1.2 on Ubuntu 18.04.3 LTS as a Docker Installation. The URL for the CMS is gergaxibo.sun.ac.za, and we have 4 clients connected to the CMS using the 2.1 version of the player. These clients are Windows 10 (Home) installs with their firewalls deactivated and cleaned up according to the Windows installation procedures on the Xibo website. The XMR settings are standard. tcp://gergaxibo.sun.ac.za:9505 is set under Settings…Display as well as Display Settings Profile for the Windows profile. The Collect interval is set to 1 minute, which is probably too low, but 5 minutes for use was too long because we use Xibo to display exam room and schedule bookings. 1 minute is not ideal (Xibo support says so) but the next available increment is too long.
So based on this I assume that our XMR is correct and working, but the issue that I am experiencing at the moment is that if I use “Collect” function to "force the player to get the new content. It often does not work, and the screen seems “stuck” on the old content. Only several reboots of the players (We use UltraVNC to reboot because sending “Collect Now” command or a “shutdown /r now” command via XMR does not seem to work (or there is no indication that it has or hasn’t worked.)
In desperation we uninstalled the Player on Windows 10 clients, de-authorised and deleted the displays and re-registered then and assigned them to the appropriate Display Groups, and eventually after 5 or so minutes the “correct schedule” appeared and this worked for a couple of days before FUBARing again.
My primary question was (with all things being equal - with XMR set up and configured correctly) are there examples of commands, and tutorials available of the correct and comprehensive use of XMR like restarting the player itself and NOT rebooting the entire Windows machine, Apart from one or two mentions (and a single Youtube video) of using “shutdown -r now” as a command I found nothing to work with.
I was concerned that Windows 10 was the issue (I hate that OS with a passion) and experimented with the Linux player (Ubuntu 18.04.3 LTS Desktop - Basic) with snap and it seemed to work well, but after a reboot of the virtual machine (using to test) after I set the snap xibo-player to run on bootup I get a “[ZeroMQ] Unsuccessful connection to http://gergaxibo.sun.ac.za”.
So I seem to be stuck at this stage.
