No connection with Home Assistant Green

I’m fairly new here and experimenting with HA, so my knowledge is basic. About a year ago, I bought a HA Green and set it up with a few basic scenes. This worked fine, and I could access the server via homeassistant.local:8123 and the iPhone HA app. Until recently, when the Hue scenes started acting strangely, I tried to access the HA, but without success. Even after several resets, there was no result, even though nothing had been changed in the network (not intentionally, anyway ;)).

I see this when I connect the HA Green via HDMI, where I don’t see an IPv4 address, which is odd. What could be wrong?

when you said reset. Do you mean restarting your HA? best thing to do is log into your router and see if HA got an ip there. Maybe give your router a reboot as well.

What is end0:? Isn’t it eth0: usually?

I think it changed to end0 somtime in last 2 years for embedded linux systems

Perhaps an update in the router caused the problem. Others have reported some routers dont play well with the green.

If I had a green with a RTC I’d put a cr2032 in it incase power failure and then when powered up again internet connection didnt come up the HA would still load.

Thanks all.
@NavNav: Indeed, restarting the HA and resetting it via the button on the back. After rebooting the router, a different message appears on the home screen, but no connection can be made.

HA is not connected directly to the router, but via switch btw.

In the meantime I found the HA ip address in the router settings, but still not able to access it (192.168.1.163:8123)

New update: I managed to log in via the HA app on my iPhone. When updating HA OS, I received a message that the update had failed and was then logged out. After a while, I managed to log in again, and the update was successful.

Unfortunately, I still haven’t been able to log in via the browser and the HA app on my MacBook (the app displays the message “You are unauthenticated,” and the Chrome browser displays “This site is unavailable”).

This is what I could retrieve from the logfiles:
