I’m currently running core-2021.4.4. I don’t recall if it was the .4 update, but within the last week I updated the Core OS. It rebooted and I assumed something went wrong because the portal never came back up. I ended up rebooting a couple more times and logging into the CLI to see if I could figure out what was wrong.
That’s when I realized that I could still connect via IP. Anyone else seen this?
Did you roll back the core to see if it’s the core update caused it? There is a new core update maybe that will fix it. Other than that do you have other mdns devices on the network? Could be something in your router.
