Check the connections
Starting at the Bosch IoT Suite Console, click the Connection entry in the left navigation.
In case it is not there, use the search, and click the star icon to pin it to your navigation bar.
Please make sure, that your connections are active. This is indicated with the plug symbol: in the example below the first connection is open and will work, the second one is disabled.
If one of your connections are closed, just open them.
