10 Players Lost All settings same time


This morning we had very big issue, all clients gone to player default. Reseted all server and etc. information on the XiboPlayer Options. So started showing Xibo Player Default Screen, wont play any video.
All connected clients had same issue at same time. But the offline clients didn’t effect.

The players which we reenter server information on the XiboClient Options, (because they have all the files) they started to play videos.
But the server side we must delete and authorize all effected clients, because they shown as unauthorized.

You Can check one Display from Cms logs; The all effected players have Activity Threshold error in the log.

Thanks for your help


We’ve seen a few of these recently and we’re not sure why. It appears that the XiboClient.xml file we store in the Users Roaming folder gets removed, causing everything to reset.

In your case it seems like the hardwareKey file stored in the library folder also got removed, causing new hardware keys to be generated.

We do not have any information for what might be causing this at present.


The problem happened all clients at the same time, does it make any idea? But clients which not connected to server at the time, they have no problem.
Thanks Dan, this is very important, because it could happen any time, no warranty.
Best, Michael.


I am not sure what you mean by this? Were those players offline meaning disconnected from the network? Or switched off?

Can you see if a windows update has been applied on the Players that were online - and if so, what does that update contain?


Some of them disconnected from internet, some of them switched off. If because of windows update, they would have same problem after get online.


I had same test on this issue.
Yes as you said if you delete %APPDATA%\XiboClient.xml (roaming folder) file, player goes to factory default settings.
If the file does not exists, Player tries to connect the server (but no server information) after 2 minutes WatchDog says “Activity Threshold Exceeded” and restart Player, this loop continues always. By the time, %APPDATA%\XiboClient.xml wont created (because no healty server connection)

If you open xibo player options, and reenter server information, (I think it recreates hardwarekey), you need to Delete&Add the player and authorize from CMS.

SOLUTION: (it saves you from the issue but I still dont know how the problem occures)
After installation of Xibo Player, goto installation folder, usually (C:\Program Files\Xibo Player) and

edit default.config.xml

Modify those rows as your information;
<LibraryPath>C:\xxx Your Library Path</LibraryPath> <ServerKey>YourServerKey</ServerKey> <DisplayName>COMPUTERNAME</DisplayName> <ServerUri>http://yourUrl</ServerUri>

When this problem happens and player goes to factory default, then Player reads information from this file, (because we add server information to this file) player get settings and could reconnect your server again. If you have all files in your Library, everything will be fine on CMS and Player side. And Xibo automatically creates XiboClient.xml file on %APPDATA% folder.

I hope this helps, but still need a real solution.
