After kafka startup sometimes I get this behaviour (not all the time - seems random).

org.apache.kafka.connect.runtime.rest.errors.ConnectRestException: Internal request missing required signature\n\tat org.apache.kafka.connect.runtime.rest.RestClient.httpRequest(RestClient.java:133)

This ~5 message of these get print to the console every seconds.

curl-ing host:8083/connectors/myconnector shows that the connector is running (max task config set to 10) howevery the task list is empty (it is NOT UNASSIGNED ,but it is empty)

At next startup it works fine
