DDUtil Error with SteppIR SDA-100

edited April 2019 in Third-Party Software
Lost in the weeds on this one. Was working -- now not.
Using DDUtil 3.2.6 and my Flex 6500 just to control the SteppIR SDA-100. "Connect to CAT" produces this error message:  
"Cat Server Connect Error! No connection could be made because the target machine actively refused it.  DDUtil_V3"  

What is that?

    That error means that DDUtil could not connect to Smart SDRCat. Suggest doing a PC re-boot which should fix things.

    Re-booted. Same error. Seems something a little more persistent. Suggestions?

    Either SmartSDRCat is not running or it has a problem. Open its UI and check to see it has a TCP port 5002 which should be a default it's setup with. If it doesn't have one create it.

    Bingo! Somehow (not my fingers) port 5002 became 6000. Changed to 5002 and we're happy. Still not talking to the SteppIR, but I think I can take it from here. Thank you so much, Steve.
