Unable to install firmware

Hello,

My new iCUE Nexus just arrived. After connecting the nexus to my PC, iCUE told me that the firmware needs to be updated. When I click the "Update" button in the message, iCue tells me that it is unable to check for a firmware update. See the attached images for screenshots.

When I look into the debug log of iCUE, I see some errors:

2020-09-17T17:48:43 W cue.firmware.index: No device FW versions were provided "iCUE NEXUS"

2020-09-17T17:48:43 C cue.firmware.index: Incorrect index contents: fw obj is empty "combined-image"

And a little further some more errors:

Does anybody have a solution for this? I am unable to use my new iCUE nexus, because the software refuses to let me modify anything unless I install the new firmware update. I am running iCUE version 3.33.246.

Thank you.
