Connection closed by client [ NUC | Ubuntu 20.04 | Virt-Manager ]

I’m running qcow2 (converted VDI) image with Virt-Manager on Ubuntu 20.04 on NUC. I’m able to start
Home Assistant (0.110.1 | HassOS 3.13) and everything seems to be running well for several minutes before access to Home Assistant hangs via web assess on port 8123.

VM Console continues to work and is accessible. I see that port 8123 is still active but I cannot access HA via the web browser
