I have an RPi server on my network running docker with containers of home-assitant, emqx, node-red, and MotionEye.
I have the Avahi on RPi setup to show the RPi on network as black-pearl.local. I have long used a Windoze 10 laptop but have now also built an Ubuntu desktop PC. I am running Chrome on both. Both the desktop PC and the laptop are both connected to the same wifi router. The laptop seems to connect readily to a url using the RPi host ID of black-pearl.local but the Ubuntu PC refuses to connect, or connects and then disconnects. The PC is much happier if I change the url in the browser to use the actual IP address of the RPi. That appears to suggest there is some problem with how Ubuntu or Chrome running on Ubuntu deals with DNS Service Discovery? Cheers, A
