<![CDATA[FOG Client and The remote server returned an error: (500)]]>Hello,

I have updated FOG server to the latest stable version: 1.5.10.1903.
FOG server is running on Ubuntu 24.04.4 LTS.

The problem is that now FOG clients are returning error:

Communication ERROR: Could not contact FOG server
Communication ERROR: The remote server returned an error: (500) Internal Server Error.

When I have checked apache2/error.log I have folowing error:

Wed Jul 22 09:45:28.388629 2026] [proxy_fcgi:error] [pid 676068] [client 10.0.0.107:54208] AH01071: Got error ‘PHP message: PHP Fatal error: Uncaught ValueError: min(): Argument #1 ($value) must contain at least one element in /var/www/fog/lib/fog/storagegroup.class.php:228\nStack trace:\n#0 /var/www/fog/lib/fog/storagegroup.class.php(228): min()\n#1 /var/www/fog/lib/client/snapinclient.class.php(160): StorageGroup->getMasterStorageNode()\n#2 /var/www/fog/lib/fog/fogpage.class.php(3306): SnapinClient->json()\n#3 /var/www/fog/lib/fog/fogpage.class.php(255): FOGPage->requestClientInfo()\n#4 /var/www/fog/lib/pages/dashboardpage.class.php(76): FOGPage->__construct()\n#5 /var/www/fog/lib/fog/loadglobals.class.php(65): DashboardPage->__construct()\n#6 /var/www/fog/lib/fog/loadglobals.class.php(79): LoadGlobals::_init()\n#7 /var/www/fog/commons/base.inc.php(38): LoadGlobals->__construct()\n#8 /var/www/fog/management/index.php(22): require(’…‘)\n#9 {main}\n thrown in /var/www/fog/lib/fog/storagegroup.class.php on line 228’

From the logs I assume that there is a problem with StorageGroup.
I have a few storage groups & storage nodes as per pictures below.

Snapins Storage group on this FOG server are set to GR storage.

Is my setup wrong?
Can you help me somehow?

I’ve pushed some code into dev-branch if you’d be willing to install and verify that your fog client functions now?
