So I decided to change from Supervised to HAOS. For that I got a new SSD, installed the OS using the RPi Imager and kept the old SSD just in case. The installation runs on a RPi4.
Which is why I assumed I could just remove the old SSD and connect the new one with HAOS.
Doing so HA starts with the usual message “Setup can take up to 20min”. But a couple minutes later my internet stops working. My router doesn’t get any connection with the ISP (sim card).
Upon checking the logs of the router (TP-Link Archer MR600V1) I find this:
On my router only the default DNS addresses are configured 212…15 + .14.
The other one 220.127.116.11 is nowhere assigned. And this error occurs everytime I startup the Pi (wired connection) with the new HA OS SSD.
As soon as I remove the Pi (ethernet cable) the router starts functioning again.
Afterwards I tried powering up the Pi without any internet connection, waited +20min, reconnected the Pi to the internet but the installation wasn’t finished. Still the setting up page.
- Do I have to reset the Pi completely? → reinstall the bootloader?
- Does HA OS need Google’s DNS?
- Does the installation process need an internet connection?
How can I resolve this?
Where do I look for further clues?
Thanks in advance!
