Updated to latest dev-branch and snapins are working now
Thansk for help.

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?

@Richarizard504 You can try to use snponly.efi or snp.efi in your DHCP 067 Bootfile Name setting.
After change I was able to perform host registration and inventory.
Hope it helps.

@Richarizard504 There was no reply for this problem.
I think this problem started with iPXE 2.0.0+ and new Lenovo ThinkPad T16 Gen 4 (model 21QFS5BE00).

@Tom-Elliott

I pulled latest dev-branch version 1.5.10.1856, re-run installer and snapins are working again.

Thank you very much for help.

@Tom-Elliott I tried 3 snapins all returned SnapinClient ERROR: Hash does not match…

@Tom-Elliott

This is the same file downloaded from the same fog server (just with powershell iwr and saved to different folder)

Hope it helps…

@Tom-Elliott said in SnapinClient ERROR: Hash does not match:

Are you able to read the file as in a text?

Yes. See picture attached.

@Tom-Elliott The file is 16MB.

Hello,

On installed FOG dev-branch version: 1.5.10.1854 I have a problem with deploying snapins.
fogclient downloads file in C:\Program Files (x86)\FOG\tmp. The size of file is usually 1kb.
In fog log i get : SnapinClient ERROR: Hash does not match

I have checked on server sha512sum and size of installation file and it seems ok.

Any help is much appreciated.
