IoX won't launch Admin Console

[JMC]

IoX Launcher finds my EISY and gives an option box which gives the options of Admin Console (LAN), Admin Console (Cloud), Polyglot and OpenADR. Neither of the two Admin Consoles work. When I click on one I see a momentary IcedTeaWeb logo but it goes away immediately and nothing else happens. I get no Admin Console, I get no icon for the desktop, and the IoX Launcher is no longer responsive.

@JMC what computer OS are you running?

have you attempted to clear Java cache? Make sure you select all three options.

Typically the third box is unchecked. By checking that box it should remove the desktop icon and underlying connection with it. Allowing it to be re-added when start.jnlp is run the next time. 

Delete any start.jnlp or admin.jnlp files on your system. Download a fresh file from the Universal Devices website (https://www.universal-devices.com/) and click on “My ISY” on the upper right of the homepage. 

Most of these directions work for Windows and macOS systems. If running something else please let us know what it is and maybe others can chime in.

OS is Ubuntu 22.04 so that box (Delete Files and Applications) is not available to me.

I clear the cache with "rm -rf /home/****/.cache/icedtea-web/cache/*"

Start.jnlp files are gone. I moved the admin.jnlp file to a USB drive and pulled it from the system.

The two Admin Consoles shown by IoX still don't work.

@JMC I think you've had this issue before. Not sure what you did to get it sorted out before. I know @bpwwer was also in on a recent post about this. I don't use that OS so can't help with what you're attempting. 

Looks like last time you removed IceTea and reinstalled and stuff worked.

Old posts you had about this (or similar):

Similar but not the same. Prior was a version mismatch. This time is just IoX not working. I tried the same solutions I used the previous time just in case but no success this time.
