Problem with mqtt loading sensors, switches (since 0.108.9)

Configuration
1

Hello,

Since the last update to 0.108.9 all my sensors, switches, lights are unavailable.
I don’t know if it is specific to this version but I encountered it when updating from 0.108.8 to 0.108.9. Does anyone has the same problem? Should I try to reinstall HA with previous version?
EDIT: It isn’t a problem with 0.108.9. When I go back to an older version the problem still remains.
MQTT is up and running (tested with MQTTfx).
This are my HA logs:

Did you check if your mqtt broker is running ?

3

Yes mqtt is up and running. I can turn on/off my switches/lights with MQTTfx when publishing to the topics.

4

Did you check in developer tools -> Mqtt if HA can talk to your mqtt broker ? There is clearly a problem between HA and mqtt.

5

Okay HA can’t talk to the mqtt. When I try to publish to a topic with HA I get an error. Fehler beim Aufrufen des Service mqtt/publish. Service not found. -> Failure calling service mqtt/publish. Service not found.

Why is the service suddenly not found?

6

What broker are you using ?

7

I’m using eclipse-mosquitto for docker in version 1.6.9. And I only can’t use it from HA, when I test it with other software I can publish and subscribe topics and it is working.

8

Try to configure it in configuration.yaml :

Example :

mqtt:
  broker: 10.0.0.63
  port: 1883
  discovery: true
  discovery_prefix: homeassistant
  username: xxx
  password: xxx

Restart HA after making the changes.

9

Thats how I did it:

mqtt:
  broker: !secret mqtt_url
  port: !secret mqtt_port
  client_id: home-assistant
  discovery: true
  discovery_prefix: homeassistant

I don’t have username and password for my mqtt broker because it is only in my local network.

10

And it works now ?

11

Sorry didn’t notice that this already was my configuration. The error still remains :frowning:

12

Do you see anything in the mosquitto logs ?

13

No activity from HA in the mosquitto logs. It seems that HA can’t even reach it.
I think HA gernerally has a problem that it can’t conntect to anything. This is from the HA log:

2020-04-27 19:26:31 ERROR (MainThread) [homeassistant.components.updater] Error requesting Home Assistant update data: Cannot connect to host updater.home-assistant.io:443 ssl:None [Try again]
2020-04-27 19:26:32 ERROR (MainThread) [homeassistant.components.mqtt] Failed to connect due to exception: [Errno -3] Try again

Here you can see that it fails to connect to mqtt and also to the weather forecast (api.met.no). Same is for influxdb.

14

run

ha dns info

in SSH and see if there are dns servers present.

15

Where is the ha command located? I have connected to the container but the command is not in the path:
bash: ha: command not found

16

Ok, your probably nor running Home Assistant supervised, but Home Assistant Core on docker. Then I don’t know how to fix HA not connecting to anything.

17

Based on your hint for dns I have investigated a bit further. The problem I’m facing is in fact not a problem related to Home Assistant.
I run HA as a docker container on synology nas. To get it connected to the internet I don’t run it on the host network but on the bridge.
I have tried to run HA on the host network and then it works.
Now I have to figure out why it has stopped working. But I think this is a docker related problem and not HA.

Thanks for your help
