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.
