Thank you, Rick.
After I made compose down and set the port 1883 open (as “sudo ufw allow 1883/tcp”), I still got the same error message.
BTW, I’ve tried different way to install the Mosquitto MQTT Broker before the Docker, Is this step leading the Farmbot Web App Server to confusion?
or should I post my ENV file for this problem?
On the other hand, I’ve experienced similar problems as “7.0.2-beta and AMQP connection timeouts” in March. After I reinstall the Ubuntu and update the file to the newest version, the problem became the title.
Is there any relationship between the two problems?
Thanks again.
