[SOLVED] Mosquitto stopped working after upgrade to v 1.5

Setup, Configuration and Use Beginners

Hello,

just did today the apt-upgrade and I saw that Mosquitto was upgraded to the version 1.5.
However, MQTT stopped working. Looking at the mosquitto.log it was the following information:

1527548294: mosquitto version 1.5 starting
1527548294: Config loaded from /etc/mosquitto/mosquitto.conf.
1527548294: Opening ipv4 listen socket on port 1883.
1527548294: Opening ipv4 listen socket on port 1883.
1527548294: Error: Address already in use

I tried to stop the service, rebooted the raspberry pi, but it didn’t work.

Any help would be appreciated!

post your mosquitto.conf

try to comment out the following lines in it:

# include_dir /etc/mosquitto/conf.d
# listener 1883 0.0.0.0
3

After commenting the lines, I could see that the connection from the devices to mosquitto were done, but MQTT is not listening to the commands, nothing is working…

my mosquitto.conf :

pid_file /var/run/mosquitto.pid
persistence true
persistence_location /var/lib/mosquitto/
log_dest file /var/log/mosquitto/mosquitto.log
include_dir /etc/mosquitto/conf.d
password_file /etc/mosquitto/passwd
allow_anonymous false
listener 1883 0.0.0.0

oh, my OH was upgraded to 2.3.0 too…

Hello,
i had the same problem, i commented out the line with “listener” and everything worked again (OH2.2, mosquitto 1.5).

I made the following modification at mosquitto.conf (I indented the listener). The devices are connecting but mqtt is not listening to the messages:

pid_file /var/run/mosquitto.pid
persistence true
persistence_location /var/lib/mosquitto/
log_dest file /var/log/mosquitto/mosquitto.log
include_dir /etc/mosquitto/conf.d
password_file /etc/mosquitto/passwd
allow_anonymous false
"# listener 1883 0.0.0.0

7

To comment out use

# listener 1883 0.0.0.0

Check your /etc/mosquitto/conf.d/mosquitto.conf for any valid listeners, for example

listener 1883

8

I did that, # listener 1883.0.0.0 (just typed wrong).

When I take out the comment the devices doesn’t connect.

Looking at the log, I can see that the devices are connecting but mqtt is not listening to the port 13

How can I know which process is using the port 1883? But as far as I know there is no process using this port.

10 
lsof -i :1883
11

lsof -i :1883

nothing appeared… so strange…

12

Any clues?

[12:28:32] pi@raspberrypi:~$ lsof -i :1883
[12:31:42] pi@raspberrypi:~$ mosquitto -p 1883
1527697965: mosquitto version 1.5 starting
1527697965: Using default config.
1527697965: Opening ipv4 listen socket on port 1883.
1527697965: Error: Address already in use

13

I tried this command:

sudo lsof -i TCP:1883
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mosquitto 480 mosquitto 4u IPv4 11931 0t0 TCP *:1883 (LISTEN)
mosquitto 480 mosquitto 5u IPv6 11932 0t0 TCP *:1883 (LISTEN)
mosquitto 480 mosquitto 7u IPv4 9968 0t0 TCP 192.168.0.2:1883->192.1 68.0.8:13146 (ESTABLISHED)

yeah. i forgot to tell you to use sudo
(I always sudo su first :))

so… the Mosquitto MQTT Broker is up and running and listening to 1833.
You also have 1 client connected

Hello, finally MQTT started to work.

I had to disable and enable MQTT Binding and comment this line:

listener 1883 0.0.0.0

After this everything went ok!!

Thanks for your help!

So you used this or commented this out with # ?
I am struggling with the same issue

EDIT: I got the connection from my phone (Owntracks) by commenting out the following

#include_dir /etc/mosquitto/conf.d

in

/etc/mosquitto/mosquitto.conf

and mosquitto still reports to listen on port 1883 (I don’t have listen in the config above).

And openhab is obviously connecting:

New client connected from 127.0.0.1 as openHAB (c1, k60, u'mosquitto').

but I get no updates in OH

EDIT 2:
I restarted mqtt transport and mqtt binding from karaf.
It seemed to have solved the issue.
The root cause (using another config than before) is still unknown.
