Home Assistant VM: Integrations that connect via TCP/IP intermittently losing socket connections

My Home Assistant VM has Integrations (Glances, MQTT broker) that connect via TCP./IP to apps/services that run on my Host PC are intermittently not able to make their socket connections. I don’t see any warnings/errors in my Supervisor log.

Does anyone have any ideas what might be causing this behavior? I’ve spent a great deal of time trying to figure out what’s causing this. I’m hoping someone much more experienced than me might have some ideas how to mitigate this issue.

NOTE: I don’t have any issues accessing the Home Assistant’s network services, such as the web interface, ssh, samba, etc. from anywhere. This is rock solid.

NOTE 2: If I setup REST sensors via the configuration file, this is also rock solid. No issues with this either.
