The problem was the IGMP Snooping as you suspected. Thank you for your help.

@Tom-Elliott Absolutely. I will get back to you in a few hours.

@Tom-Elliott

Yes, it looks like multicast is working correctly. Thank you for the support.

I also want to add a few details to clarify our setup.

A few months ago, I was running version 1.15.10. Since we are developing an API-based solution, we decided to upgrade to the latest development branch.

During the upgrade, I noticed that when the message appeared telling me to visit /fog/management to update the database, no database update actually took place. Instead, the web interface took me straight to the FOG login page.

If I understood that correctly, it suggests there were no database schema changes between 1.15.10 and 1.6. However, that later led me to question my understanding, because several issues arose afterward, including the one mentioned in this post: “Database Update: Failed.”

I will add the other issues to the forum soon and link them here.

@Tom-Elliott

FOG version: 1.6.0-beta.2273

Let’s ignore the Snapin errors for now. The error is thrown at the end of the Multicasting image.

@Tom-Elliott

FOG version: working-1.6
commit: f61a90d97

The history of the days we noticed the issue. One thing I want to point out is that unicasting doesn’t throw that error.

@Tom-Elliott Hi Tom, Sorry, my bad. I don’t get Login incorrect message. Mine is saying, No active task found for Host <Hostname>. But the error is the same, could not Update database. Also, I am using the latest working-1.6.

I don’t know if these errors are relevant, but my Multicast was around 12:30.

@JGeear, I have the same problem. But I’m running the latest 1.6-working version.

@Tom-Elliott Hi Tom,

Thank you, that clarifies a lot. I now understand that hostSecTime represents the expiration time, not the creation time, which fully explains the consistent +30 minute offset I was seeing. That part now makes sense and resolves my question.

The only remaining actual issue I’m trying to understand is the snapin behavior: in several cases, snapins did not execute on some hosts. I don’t see any errors in the logs. Only that the snap-in task doesn’t start, but I will work on this and gather some more data. Thank you!

@GRISLET

Hi,

I am not an expert on the technicalities, and someone with more experience may be able to explain it better. However, I can confirm that there is no issue capturing and deploying Windows 11 with FOG 1.15. I capture and deploy Windows 11 weekly without any problems. I mainly use the Single Disk (Everything) option, but I have also used multi-partition successfully.

Based on your description, it sounds like your configuration is not capturing the boot partition. As a result, when the image finishes deploying, the system cannot find a valid boot mechanism and falls back to network boot.

I am not aware of any completion message on the server. As far as I know, once the progress bar in the Task tab reaches 100%, the image has been fully cloned to the computer. Can you confirm if that is what you are seeing?

Hello,

We are seeing a persistent encryption/token issue in FOG 1.5.10.16. There is also a consistent timestamp anomaly, and while both occur together, I do not know if they are directly related.

Problem 1:

Every time the FOG Client authenticates (for example, after a reboot), a new token is generated, and shortly after that, the “Reset Encryption Data” button reappears automatically in the UI.
I am not sure if this is expected behavior by design, but I have observed that some snapin tasks do not execute unless the encryption data is manually reset first.

Problem 2:

Separately, there is a consistent +30 minute offset between the database value hosts.hostSecTime and all real system clocks. The offset is always exactly +30 minutes ahead of:

hosts.hostSecTime in MariaDB is always written exactly +30 minutes ahead of: FOG server time (date), MariaDB NOW(), Windows client time (Get-Date), token.dat LastWriteTime on the client.

Example data from Host with ID 66:

PS C:\Users\Administrator> Get-Item "C:\Program Files (x86)\FOG\token.dat" | Select LastWriteTime

LastWriteTime
-------------
03/12/2025 9.45.58

And

MariaDB [fog]> SELECT hostSecTime FROM hosts WHERE hostID = 66;
+---------------------+
| hostSecTime         |
+---------------------+
| 2025-12-03 10:15:58 |
+---------------------+
1 row in set (0.000 sec)

All systems (FOG server, storage node, Windows clients) are correctly NTP-synchronized.

Questions

Is it normal for “Reset Encryption Data” to reappear after every reboot?
Is the +30 minute offset in hostSecTime expected or a known issue in 1.5.10?
Could either of these independently explain intermittent snapin failures?

Cheers!

@Tom-Elliott Hello,

I’m experiencing the same issue with the settings. Now that the fix has been pushed, what’s the correct way to resolve it?

Do I need to reinstall FOG, or is pulling the update and restarting sufficient?
