Integrations that connects to Host machine not working on HA OS in VM

Hello everyone,

I just moved from a Raspberry Pi, because really unstable and slow for me, to HA OS in a VM on a Ubuntu Server Machine. In general everything works fine and better, but from what I’m seeing all the integrations (Transmission, Glances, Plex recently added, etc.) that connects to the Host machine, the Ubuntu Server, where the VM is running do not work. For example next can be seen the error of such an integration by saying that the Host is not available, even if it is exactly the the same machine where the VM is running.

The VM is using Direct Attachment as Network Interface so on my router I see my Home Assistant OS with a different IP address.

Does somebody knows a fix for this?
