Connector name (If you need help with some connector/converter): no connector

Error traceback (If it was raised):

[tb_client.py] tb_client connect 288 connection refused, check thingsboard is running

while on the thingsboard ui at localhost:8080, the iot gateway is active shown in the dashboard

Hi, there is a config setup you need to configure. /etc/thingsboard-gateway/config/tb_config.json you need to specify where you want the gateway to report to ... in my case the TB Server CE . then you need to create a gateway device into the TB Server, get the credential to place it into the file mentioned above. Once you have that... then you should create a dashboard to see if the gateway is connected. it is so tricky, I have spent over a month so far. I can send data and RPCs from TB Server... let me know If you managed to install the gateway using which method, each method has its own difficulty...

hi @tatuiot I am having the same issue while trying to connect gateway with thingsboard, I am using community edition thingboard and following the same approach as given in documentation but getting this error |ERROR| - [tb_client.py] - tb_client - connect - 288 - Connection refused. Check ThingsBoard is running. And also can you tell how many connector can I connect with one gateway in thingsboard community edition

Hi,

If you are running the gateway using the docker compose and ThingsBoard in the docker as well - please try to use host.docker.internal instead of localhost as host in tb_config.json. Because in case of connecting to localhost, when the gateway is in container - it tries to connect to local address inside the container.
