## The issue
|
|
|
|
Home Assistant needs to know when it has a stable network connection in order to disable functionality which requires that.
|
|
Without this check you will face an increased number of errors and performance issues due to connection timeouts.
|
|
|
|
## The solution
|
|
|
|
From the host shell, first execute the following:
|
|
|
|
```sh
|
|
busctl get-property org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager ConnectivityCheckAvailable
|
|
```
|
|
|
|
### Output is `b true`
|
|
|
|
You just need to re-enable connectivity checks by executing this command:
|
|
|
|
```sh
|
|
busctl set-property org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager ConnectivityCheckEnabled b true
|
|
```
|
|
|
|
It may take a bit for the message to go away as all checks are scheduled on timers. You can force it to recheck immediately by executing the following commands:
|
|
|
|
```sh
|
|
ha host reload
|
|
ha resolution healthcheck
|
|
```
|
|
|
|
### Output is `b false`
|
|
|
|
You need to set the connectivity uri in Network Manager's config. You can do this by adding the following to `/etc/NetworkManager/NetworkManager.conf`:
|
|
|
|
```txt
|
|
[connectivity]
|
|
uri=http://checkonline.home-assistant.io/online.txt
|
|
interval=600
|
|
```
|
|
|
|
Afterwards you will need to restart NetworkManager by either rebooting the host or executing this command:
|
|
|
|
```sh
|
|
systemctl restart NetworkManager
|
|
```
|
|
|
|
As mentioned above, the checks are on timers so the message may not go away immediately unless you force an immediate re-check. If you continue to see the message after a while or after forcing a re-check then start over at the top of this solution. You may need to separately enable the check now that it is available.
