Hardware: RaspberryPi 3 connected via ethernet
I was attempting to install HACS and I kept getting a resolve error. Upon further inspection, it goes beyond HACS.
I attempt to ping google.com and I get: ping: bad address ‘google.com’
I did a dig google and I get communications error to 172.30.32.3#53: timed out
I have set the DNS manually to 8.8.8.8,1.1.1.1 and I’ve repeatedly reset the hardware and reset DNS specifically.
I eventually did ha dns downgrade and everything started working - but this only seems to last for a few minutes. If I go back in 5 minutes or so and do a ping I get the same errors.
Home Assistant was working prior to this popping up randomly. I made no changes to my router, and the router is in the default state.
Additionally, HA works when I manually downgrade the DNS and then stops working when some unknown service breaks it later. If it was something with my router, wouldn’t the problem always be there?
I have a second router that I use as a bridge to provide wifi out to my garage, but it has been there the entire time and the HA instance is conencted via ethernet.
Turn off while debugging this issue to see if it improves.
The devices get information about what IP, subnet default gateway, DNS servers and so on they should use.
A device might get the information from the correct router, but then the other router later discovers the device and sends a new set of information which is buggy.
No, I am not.
I am pretty sure it is related to your network and not really HA, unless you have installed a DHCP or DNS service addon on the HA.
The extra router is just a common occurring issue where configuration of the services are often done wrong, like connecting both the two routers on the network on one of their LAN ports and not making sure that DHCP and DNS is surely disabled on one of the routers.
DHCP is disabled on the second router. Also, it was working until recently. I made no changes to the network - it is as it has been and it has been working. Also, all other devices are working and able to ping and access the internet without a problem - including another pie running Raspbian.
