I need some help connecting a Thingsboard IoT Gateway with my Thingsboard Instance over a TLS 1.2 secured connection.
Thingsboard and the IoT Gateway are running on separate machines. Thingsboard is configured to only accept TLS 1.2 secured connections.
I started with the configuration of the IoT Gateway by following the "Getting Started" section in the documentation (https://thingsboard.io/docs/iot-gateway/getting-started/). This ended in an error message like:
2019-02-13 15:20:24,796 [main] ERROR o.t.g.s.gateway.MqttGatewayService - Unable to connect to ThingsBoard. Connection timed out after [10000] milliseconds
Reading some issues on GitHub I figured out maybe there has to be a specific configuration with keystore files. The target Thingsboard server is using a Let's Encrypt certificate. And in my JAVA cacerts keystore, the ISRG Root X1 certificate is included. Will the IoT Gateway not use this keystore? Do I have to provide a dedicated keystore file for the IoT Gateway?
Looking at the configuration page (https://thingsboard.io/docs/iot-gateway/configuration/) I still have a lot of questions. I never worked with keystore files and therefore I don't have any clue what certificates I have to add to a keystore file and how this is done.
This is my current tb-gateway.yml configuration:
server:
# Server bind address
address: "0.0.0.0"
# Server bind port
port: "9090"
# Check new version updates parameters
updates:
# Enable/disable updates checking.
enabled: "${UPDATES_ENABLED:true}"

Can someone give me a more detailed explanation than the Thingsboard documentation?
