Using Segger J-link plus with FRDM-KV31F. Target machine actively refused it.

When I try to use the Segger J-Link plus with an FRDM-KV31F I get the following message.

"localhost:2336: No connection could be made because the target machine actively refused it."


In the console I get this, "Checking target voltage...  Connecting to target failed. Connected correctly?

GDB Server will be closed..."


I attach a photo of my connection - Have I done it right?


If I have, any clues as to what is going on?


I also am attaching the messages generated.  The first window message is also duplicated in the console.


I've also attached the Configuration for the Segger probe in MCUXpresso.  If I change from SWD connection to JTAG the results are the same.


Thanks for your help.
