[HELP] How to deploy dockerized both TB server and mqtt gateway on same machine

[devaskim]

Describe the issue I understand that it is network port issue but don't know how to solve with minimal reconfiguration. Gateway receives data from broker, but cannot connect to TB server due to timed out

Configuration (Attach your configuration file) Defaults for TB server and gateway MQTT configuration (1883 port)

Connector name: MQTT Connector

Error traceback (If it was raised):

TimeoutError: timed out
""2022-11-12 12:14:08" - |ERROR| - [tb_client.py] - tb_client - run - 177 - timed out"

Hi @devaskim you have to had two separate MQTT brokers (one for ThingsBoard and another one for Gateway). Also these two brokers have to be run on different ports.

@samson0v I am not sure that understood you. Would it be enough to run TB server with MQTT port changed to, for example, 1882 and to set this port in gateway's tb_gateway.yml? Because it would be a pain for us to reconfigure remote MQTT broker where our devices push its telemetry.

@devaskim, any updates?

Well, I tried suggested by me solution, but no luck. Maybe I was wrong in configuration. Now we are running gateway on our free machine, so I think I close this issue till next attemp)
