No upgrades available

Hi,

I realise this has been asked before, but all the responses I've read don't appear to match my issues.

My XG is currently on SFOS 18.0.4 MR-4

Going to System > Backup & Firmware > Check for new firmware results in the message:

"No upgrades available".

I know several updates have been released and I am sure, in the past, It's listed them all and I have been able to choose which one to apply.

Tailing /log/u2d.log shows:

I can reach https://u2d.sophos.com from my network.

My device is not connected to Sophos Cloud - because I can't log in, yet I can log into this forum.

Any ideas about what is going wrong?

T.I.A.
