Greengrass SecureTunnelling failing to start tunnel 2nd time

Using the SecureTunneling compnent 1.0.16 I had opened a tunnel previously, and this had worked, and then later on tried to open another one and found it failed continuously. Closing the previously opened tunnels didn't help. After I manually restarted the component with greengrass-cli component restart -n aws.greengrass.SecureTunneling I was able to connect. I found in the logs the error messages below - is this a known issue, or is there a way to address this problem ?

The compnent configuration was completely default as below

Component Name: aws.greengrass.SecureTunneling
    Version: 1.0.16
    State: RUNNING
    Configuration: {"accessControl":{"aws.greengrass.ipc.mqttproxy":{"aws.greengrass.SecureTunneling:mqttproxy:1":{"operations":["aws.greengrass#SubscribeToIoTCore"],"policyDescription":"Access to tunnel notification pubsub topic","resources":["$aws/things/+/tunnels/notify"]}}},"OS_DIST_INFO":"auto"}
