Streaming update problem for specific laptop

Hi all,

I have 5 laptops connected to Avast Free and they all work fine. Update, keep me protected and the streaming updates happen. However, on one particular laptop, the streaming updates do not happen.

The VPS updates fine but apart from that no streaming updates take place. My VPS is set on automatic and streaming updates are available too. However, no [streaming] updates never arrive. I have done a clean install twice now and it has not resolved the issue. I used the Avast Uninstall utility and the Avast Cleanup Tool to get rid of all remnants but that did not fix the cause.

My security setup I use is Comodo Firewall 6 (all my PCs use it and update fine), Malwarebytes Pro alongside Avast Free.

Any help would be appreciated.
