I wrote this maybe it helps somebody.
My software system is running on ubuntu 24-04 which crashed when I attemped to upgrade.
I found the IOC would not render at all.
Long story short I could create an MX project and the IOC was created correctly but when I transitioned to the cube IDE the IOC would not render.
I found this! I got java lang issues and eclipse editor issues than looking in more detail Iistening on port 41 which seemed to get no response. The rendering hung with no response - is the eclipse https site there?
This I then moved to a virtual machine so I could keep resetting after a crash.
Well I turned off the network so it now had no network connection and I got a message about the keeping it online for a better experience. Well in preferences there is also an offline checkbox - enable that and now my IOC's render fine.
This is Cube IDE 1.19.0 and Cube MX 6-15-0 runing on Ubuntu 24-04.
Note also:- had to "sudo apt install python3-tk" to install a module missing from python.
I also did the create in MX, then jump to the IDE but it was driving me nuts on how long this took.
