Reboot not working

I’m setting up GenieACS to work with some Zyxel CPEs. Everything works fine but the reboot doesnt. All that happens is a connection request but as far as i can understand it doesn’t send a reboot request. If I do a factory reset everything works as expected.

It makes no difference if the task is done through the API or the user interface.

Here’s what is logged when I do a factory reset:

2025-10-29T14:25:44.484Z [INFO] -EX3301%2DT0-: Inform; cpeRequestId=“” informEvent=“4 VALUE CHANGE,6 CONNECTION REQUEST” informRetryCount=0
2025-10-29T14:25:44.810Z [INFO] -EX3301%2DT0-: ACS request; acsRequestId=“19a305c43fd0000” acsRequestName=“GetParameterValues”
2025-10-29T14:26:34.699Z [INFO] -EX3301%2DT0-: Inform; cpeRequestId=“” informEvent=“4 VALUE CHANGE,6 CONNECTION REQUEST” informRetryCount=0
2025-10-29T14:26:34.991Z [INFO] -EX3301%2DT0-: ACS request; acsRequestId=“19a305d08260000” acsRequestName="FactoryReset

And here is what gets logged when I do a reboot

2025-10-29T14:25:44.484Z [INFO] -EX3301%2DT0-: Inform; cpeRequestId=“” informEvent=“4 VALUE CHANGE,6 CONNECTION REQUEST” informRetryCount=0
2025-10-29T14:25:44.810Z [INFO] -EX3301%2DT0-: ACS request; acsRequestId=“19a305c43fd0000” acsRequestName=“GetParameterValues”

I dont have devices from other Manufacturers to experiment with, but this happens on all Zyxel models that I have available.

Anyone gotten this to work with Zyxel CPEs?

Enable debug for the CPE in question, and then try and reboot it. Do you see the reboot request in the debug file?

I have many Zyxel’s, including the 3510 and they all reboot just fine.
