I am also getting this error on any request out to the internet eg any weather sensor. I have duckdns, let encrypt, Mqtt, owntracks, dnsmasq installed and they all seem to be running fine but I suspect the all internet connection requests going out are to an address on port 443 which might be wrong. Is this something to do with ssl or dnsmasq or a router setting?

It seems to be dnsmasq which seems to be causing the problem as when I stop the addon everything works again.

How should my dnsmasq configuration be like? I have the following…

{
“defaults”: [
“my isp server dns”,
“8.8.8.8”
],
“forwards”: [
{
“domain”: “hassio.local”,
“server”: “192.168.1.2”
}
],
“hosts”: [
{
“host”: “myservername.duckdns.org”,
“ip”: “192.168.1.2”
}
]
}

well i don’t have dnsmasq :stuck_out_tongue:

5

I am not using dnsmasq either and am seeing MANY connection errors (not 100% erros, but many). Any suggestions?

6

I have a similar problem. Sometimes, there seems to be a complete blocking of all outgoing connections from HA, when dnsmasq is enabled.

Did you ever figure out what was causing your issue?

7

For me it was dnsmasq which was the problem. I found out if you disable the component the connections could get out and then reenable the component things would work for a while until somthing times out. In the end my router was replaced as part of an upgrade which allowed internal forwarding which meant I didn’t need to use dnsmasq anymore.
