I have a DreamPi provided by "dreamcastlive" a long time ago and it worked great.
I had updated DreamPi (few year ago) but could not connect anymore. Clock update errors.
In short, I correctly re-installed my DreamPi but now I can no longer register for the Dreamcast now.
In the Rasp console everything is ok, but only one thing is in [FAILED]"Failed to start dhcpcd on all interfaces"

I have configured in my box the fixed IP for the DreamPi, It is recognized and is accessible. ping tests ok between my PC and the DreamPi

and i can see my DreamPi in my Internet Box (DMZ configured for my DreamPi).
My modem has both LEDs on. "OH" is on steady and "Data"is flashing very quickly.
I trying to disconnect my Firewall and is still the same, Detection Failed!
Any idea?
Many thanks in advance.
