Everything was working fine for the last 3 months, but yesterday without my changing any of them network settings or anything else, the Pi suddenly stopped receiving IPv4 address, as well as being accessible in the browser at musicbox.local.
I don’t see anything strange in the logs.
ifconfig I see only the IPv6 address.
I also did not change anything on my router and before it was working fine. I had added the Pi MAC address for a static IP address, but now it seems broken.
How do I troubleshoot it?
