Proxmox VM - unable to update HassOS from 4.12

I’m running a Proxmox VM (deployed a while ago with the whiskerz script) and it won’t update. It waits for exactly an hour than fails:

21-01-27 14:26:35 INFO (MainThread) [supervisor.hassos] Fetch OTA update from
21-01-27 15:26:35 WARNING (MainThread) [supervisor.hassos] Can't fetch versions from

Traceback (most recent call last):

    int_ota = await self._download_raucb(version)
  File "/usr/src/supervisor/supervisor/", line 97, in _download_raucb
    raise HassOSUpdateError()

Trying to update from the CLI results in the same error log.
The Core updates successfully from the GUI.

I searched extensively for this problem but only found suggestions for updating through USB boot, nothing about VMs.

I tried downloading the .raucb file using wget inside the VM and it downloads fine, although it stalls multiple times and I have to restart.

Is there a way to executing the update file from the CLI?
Is there anything I’m missing?

The NIC is DHCP with a reservation on the DHCP server.

Thanks in advance
