MQTT Error

[justgraduated2008]

I've been trying for several nights to get things up and running with Event Server. I have several monitors running in ZoneMinder but when I run zmeventnotification it exits after the first MQTT tick interval passes with the following error:

Expected 'PeerService' at /usr/local/share/perl/5.26.1/Net/MQTT/Simple.pm line 159.

Also what's interesting is it doesn't seem to respect the config file if I turn off MQTT in the config file. The only way I can get it to turn off is if I comment out the enable line and it takes the default of off... I've tried off, 0, false.

I would like to push the notifications out via MQTT but can't get past this. I know the MQTT server is working as I use it for several other projects ( eclipse-mosquitto:1.5.4) Here's what I've tried:

- Running from Master branch
- Running from Stable Branch
- DNS name for MQTT server(include port and don't include port)
- IP Address for MQTT Server (include port and don't include port)
- Reinstall MQTT Perl module
- downgrade MQTT Perl Module
- Reinstall socket module (seems like that's the interface it's unhappy with)
- Downgrade socket module

Here's the output:

Any insights on how to get MQTT working?

[BruceHowells]

Probably not what you want to hear, but I ran into this and found your post doing searches for a fix.

In my case, I'm running the mosquitto and zoneminder containers on the same host. When I specified the IP of the host itself, I got the error you describe; when I used 127.0.0.1, all was happy.

There's a lot of conflicting information about how to manage this kind of "hairpin" - much of it conflicting and platform specific.

For me, I'm going to go forward with running the mqtt container alongside my zm container, with vmeventnotifcation using 127.0.0.1 as the server, while (in my case) the Homebridge server on a different host will use the ip of the Docker host.

[justgraduated2008]

@BruceHowells - what network mode is ZoneMinder running in? I got the MQTT connection to work when I switched to Managed and specified a service link... but half of my monitors stopped working in that mode.

I've tried running in host and bridge mode and specifying 127.0.0.1 and still didn't work. I've even spun up another MQTT server on separate host to eliminate the hairpin and still is unhappy.

What OS are you hosting the containers on? Docker version?

I know this is an old thread but I'm having the same issue, all seems to be set up correctly but nothing is coming through on my mqtt listener.
Mqtt true - password, broker, name all set correctly.

even ran 'perl -MCPAN -e "install Net::MQTT::Simple"' to be sure.

Not sure what else to do now.

zm running in a proxmox container. broker on another container on the same host/node.

Anything look wrong in my debug output?
