This is why I support you as a member of your Channel. It always save me time when I need to do something in Home Assistant.

Nice, worked for me, Using mqtt/Nodered/Homeassistant in docker on RPi4 all of a sudden just stopped, only after digging around found the 2.x upgrade messed it up. Your vid has got me back up and running again. Thx for posting.

[jedivino]

Thank you. Yet another quick fix for my running config applied. Excellent guide as always!

Hi BeardedTinker,
I'm running into a similar problem here to Mike Nexus.
After the MQTT update I reinstalled the Mosquitto broker 5.1 because I was unsure, this action was apparently a bit too fast.
The installation was successful, I see the addon_core_mosquitto container listed with the rest of the containers. The only problem is that I cannot start this container, the following error is displayed in the system log:

2/21/12 11:06:06 ERROR (SyncWorker_4) [supervisor.docker] Can't start addon_core_mosquitto: Error 500 Server Error for http + docker: Server Internal ("OCI runtime create failed: container_linux.go: 345: starting container process caused" exec: \ "/ dev / init \": stat / dev / init: no such file or directory ": unknown")



(btw, the docker folder on my Synology Volume 1 is completely empty, at least I don't see anything, ... weird, ... maybe the files are hidden ...)

Do you have any idea how to fix this problem?
Thanks in advance,
Benny

Absolutely great! But please clarify me "listener 1883 ip_addr". In my case it runs without IP, but with IP of the server I got error in log (Error: Address not available). I understand IP should be IP of the Mosquitto server. Am I wrong?

[andychrest]

Thanks for the help. This worked. I must of had a typo like you suggested in your other video.

[RamBoZamBo]

Works great in my local network. How can I enable IPv6? My ISP has shared IPv4 addresses, so I can't connect to my network from outside via IPv4 ("Dual-Stack Lite"). I guess I should set-up authorization anyway before I make it available from the internet...

Thank you for the Vid. I am just starting out with IoT + MQTT + Docker. I did wonder why my first little project just stopped working!

Hi, I have the same issue with mqtt. I used your video "... Synology - #004" video to install mqtt. Everything was great until the recent security change. The problem I'm having now with your update is that there is no config file under docker/mqtt/config. Actually, I also have no files under mqtt/data and mqtt/log using DSM file station or putty so I am unable to update the config file. I can see the logs using portainer version 2.1.1. Do you have any suggestions? Thanks.

[jonatanpn]

I was getting the same error and then I was getting "Error: Invalid persistence value (true"
In my case the solution was to convert the configuration file to unix format

[philou]

I can't start mosquito broker 5.1.1 in docker on Synology, any idea please?

[sbaechler]

I noticed the default paths also changed from '/mqtt/' to '/mosquitto/'.

[Varian-Killbot]

This did not fix the problem for me. It opens the listening sockets (the log shows that) and then proceeds to continue to do nothing when receiving commands.
