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

RE: Reset Encryption Data” keeps reappearing + hostSecTime always 30 min ahead (FOG 1.5.10)posted in General Problems
@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!

RE: Issue when I tried to make Windows 11 gold imageposted in Windows Problems
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?

Reset Encryption Data” keeps reappearing + hostSecTime always 30 min ahead (FOG 1.5.10)posted in General Problems
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.hostSecTimeand all real system clocks. The offset is always exactly +30 minutes ahead of:hosts.hostSecTimein MariaDB is always written exactly +30 minutes ahead of: FOG server time (date), MariaDBNOW(), 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 9.45.58And
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!

RE: Change FOG Settings in working-1.6 not workingposted in Bug Reports
@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?

adding netboot.xyz to FOG menuposted in General
Hi,
I discovered that netboot.xyz offers a simple live installation. Can someone guide me on how to load the correct Netboot.xyz in FOG so I can install my desired OS? By that I mean have a FOG menu entry that loads the correct netboot.xyz file.
Thank you!

FOG Multicasting speed drops to zeroposted in General Problems
Hi everyone,
I have three rooms, each containing several identical computers. These rooms are all on the same VLAN, connected across multiple switches without any router in between. Multicasting works successfully in one of the rooms where I have two test computers. However, in the other rooms with more computers, the multicast starts fine but drops to zero speed at around 80% completion, causing FOG to disconnect the clients. Our IT department informed me that IGMP snooping is enabled on the switches. Does anyone have suggestions on what I should do?
Thanks!
Here are the multicasting logs from FOG:

Thank you for your reply. I didn’t try your solution but after IGMP Snooping was configured on the VLAN, the multicasting worked immediately.
I left all the Fog multicasting settings as default.

General question about Multicasting.posted in General Problems
I’m having trouble with multicasting and suspect it’s because there are several switches between the Fog server and the host computer, even though they’re all on the same VLAN. After checking the documentation, I’m still unsure which port numbers need to be allowed for multicasting to work correctly. The Web UI indicates that port 63100 is the default for broadcasting, and Udpcast uses port 9000 and port 9001.
I’m not an expert in networking, so I would appreciate it if someone could tell me if I need to ask our networking team to open specific ports on that VLAN for multicasting. Any other advice would also be very helpful. Thank you!
