Porsche Home Energy Manager firmware upgrade

[CatWithBat]

Has anyone see this error when upgrading the HEM?

New HEM; old one was faulty. Came with old 0245 firmware but stubbornly won't upgrade to the latest 0260 firmware.
I've tried setting it to automatic, Chrome, IE, Edge and Firefox browsers all with the same result - no upgrade.

The unit is trying to pull an image over the internet to do the upgrade. My network is working fine - the HEM has linked with my Porsche ID.
HEM has a wired Ethernet connection, but same result if using WiFi.
I don't have a local copy of firmware or know where to get one but would like to try that if anyone has a local copy.

Could it be region specific (not helpful I know) and whilst available in Australia it isn't actually intended to be applied? Is there a README file associated with the latest firmware file which might help?

Agreed firmware could be region specific so flashing a copy through unofficial sources could be risky.
Previous HEM had the 0260 firmware which it had applied through automatic update so I know there is an AU version.
