Wake-on-LAN no longer working on v21.6, likely due to MAC address being erased after update

Simon 2 weeks ago updated by Rivers yesterday at 11:18 a.m. 9

Ticket 14662263

See the image below. Since the update, if you try to wake an offline machine, the QueuedWake action is stuck in pending without ever being processed.

I think I know why. If you see the MAC Address field, it's blank. In fact, all my machines, online and offline, have that field blank.

It seems that on v21.6, the server isn't receiving new MAC Address information from the remote machines. Nor is it retaining the old MAC Address information (for offline machines) that should be stored somewhere.

And without the MAC Address information, I presume the machines in the same network can't send the WOL magic packet to the relevant machine, like trying to deliver a letter without knowing the house number.

EDIT: I reverted my instance back to v21.5 and the MAC Addresses are now restored and the Wake function is working again. So this is definitely a bug introduced in v21.6.

Hi All,

The stable release is ready for download now. Please upgrade your instance to the newest build and confirm.

Good day !!

Please remove the "Stable" designation from 21.6.3172.7787 on the Cloud Administration Page so that the reverted instance doesn't auto-update again to this faulty version.

And please release a patch soon.

We are experiencing the same issue. Please fix ASAP.

We are experiencing the same issue. Severely impacting our ability to manage our endpoints.

Same issue here, no MAC addresses, though we don't use the WOL feature much, but the missing MAC addresses needs to be addressed, any ETA on a fix?

I talked with the connectwise support about this and they could not give an ETA but said it was high priority. Shrug...

Hi All,

We have fixed this issue and is available for manual upgrade. Kindly, upgrade to the latest version and confirm.
