Mosquitto cannot start up properly

[jaceks2106]

Hello,

I have a problem with running whole infrastructure on localhost using Docker. After successful fetch and installation of all services, I noticed, that backend os2iot-docker_os2iot-backend (port: 3000) cannot run properly - the last error terminates the whole app:

[Nest] 19 - 06/17/2021, 11:01:13 AM [GenericChirpstackConfigurationService] GET http:https://chirpstack-application-server:8080/api/network-servers?limit=100&offset=0 got error: Error: connect ECONNREFUSED 172.20.0.12:8080 +17ms

Then I started investigating what's happening in service os2iot-docker_chirpstack-application-server (port: 8080)

time="2021-06-17T11:27:21Z" level=error msg="integration/mqtt: connecting to broker error, will retry in 2s: Network Error : dial tcp 172.20.0.7:1883: connect: connection refused"
time="2021-06-17T11:27:23Z" level=error msg="integration/mqtt: connecting to broker error, will retry in 2s: Network Error : dial tcp 172.20.0.7:1883: connect: connection refused"
time="2021-06-17T11:27:25Z" level=error msg="integration/mqtt: connecting to broker error, will retry in 2s: Network Error : dial tcp 172.20.0.7:1883: connect: connection refused"
(...) and so on

Port points me to Mosquitto os2iot-docker_mosquitto (port 1883):

1623927668: mosquitto version 2.0.11 starting
1623927668: Config loaded from /mosquitto/config/mosquitto.conf.
1623927668: Starting in local only mode. Connections will only be possible from clients running on this machine.
1623927668: Create a configuration file which defines a listener to allow remote access.

1623927668: Opening ipv4 listen socket on port 1883.
1623927668: Opening ipv6 listen socket on port 1883.
1623927668: Error: Address not available
1623927668: mosquitto version 2.0.11 running

I found similar issue at this link eclipse/mosquitto#2040 and they say that line listener 1883 should be added to Mosquitto configuration file, but there is no such file in this solution.

Reproduction steps:

1. Download all 3 repos
2. Go into docker repo and run docker compose up

Hi @jaceks2106,

Thank you very much for letting us know - by doing so you help improve OS2iot.

We will asap make a quick fix thats locks the version of Mosquitto to v.1.6.

When we are ready, we will then make the needed changes to update to version 2.0

Is it working in your end as well now? @jaceks2106

I have tested it @Joiversen on hotfix branch from this PR and it works :). Thanks for the quick response :)
