Hi.
So I installed Adguard Home on a separate Raspberry Pi and specified that as the DNS server to my TP Link router. Another Raspberry Pi running Home Assistant is also connected the same router and has stopped working (homeassistant.local:8123
returns ERR_CONNECTION_REFUSED
) after I added the DNS as DHCP. I then removed the DNS server IP from the router configuration, rebooted the router and manually rebooted the HA Pi. The HA URL on port 8123 is still not working and returns the same error.
I have absolutely no idea what could be causing this as I have not changed anything else on the router apart from adding the Adguard DNS IPs as both the primary and secondary DNS DHCP as well as a DHCP reservation for the Pi running Adguard Home.
Please help!
