Are you using Pi-Hole or some other network-wide blocker or have rules set up on your router/firewall? If you SSH to your Home Assistant system can you ping google.com or home-assistant.io?
Take a screenshot of what HA is showing you have configured your network as and post it here? Also, on a computer take a shot of your computers network settings? If you do that we can help you determine that.
Well, your network is not incorrect. According to those settings you are on the correct network and, since I assume you are on here from that computer, your DNS server appears to be OK as well. I presume that since your gateway and DNS servers are both 191.168.1.1 that it’s a router that is providing DNS. What happens if you change the Home Assistant DNS to 8.8.8.8?
That is interesting, as is the earlier statement “lost connection altogether”. I wonder if the router might be an issue or the load on the rPi. But you totally reinstalled HA on the pi didn’t you?
Is Home Assistant wired or wireless? If wireless you could, as a test, connect it to your phones hotspot to see if there is any difference and if there is then you know its the router, if not then it’s the rPi or the installation of HA on it.
I did a clean install again on a ssd, it is a wired connection, must be the settings in the configure network settings, I have tried 1.1.1.1 I will reset the router tomorrow.
Hey -
This worked for me with the same issue.
I’m using PiHole on my network as the main DNS, but not quite understanding how DNS is effecting the add-on installer? Thanks!
I had this occasionally over the past few month and again just now.
What worked for me:
Go to: Settings → System → Network.
Change IP4 from automatic to static while not changing any values.
save
retry → works
I can only assume the in my case it’s like this: I use Adguard Home on HA itself. I guess sometimes Adguard has not started when HA (re)starts and the update component of HA remembers that instead of rechecking and thinks it’s offline. ‘Changing’ the network settings (while not changing them) apparently resets the offline flag and the updater works fine.
