Double Switch Updates - Cannto update recently installed updates

[Nanis 1]

I installed a few double switch modules. I am on update 5.190. I can see there are some updates for them but everytime I try to start the updates, I get an error message "Error when downloading the file"

 

Any idea why?

In order to make firmware updates for a device, move the device close hc3 or hc3 close to the device. You can only update multiple devices one by one. I recomend to restart hc3 after every updated device. Sometimes it helps to delete the browser history or use another browser. I'm using Google Chrome browser for Fibaro.

Thank you for your response.

 

Well, the devices are installed in the light switches so I cannot move them! And I have a few which were installed before and i was able to update them at the time with no issues.

 

I will try the restart idea though
