I've had my insteon / ISY home running for over 10 years with very little issues, recently I've had a few switches failing to operate by voice (Alexa) or Mobilinc commands but work by using the switch itself, anyway, need to replace them and re-address but I can't get the admin console to open, I had never tried launcher but can't get it to load either. The AC seems to pop up for a split second then close. I'm on 5.3.0 with a Mac running Big Sur 11.4 and deleted/ reinstalled the newest JAVA version, cleared the . I have a relatively new Windows 10 laptop but can't get any this running on that either. The Portal does work though.
I've tried following the troubleshooting instructions to know avail, I never seem to have any luck with Java.
Any suggestions of what to try next......on either computer?
