I am also facing the same issue.
While I try to launch the Databus apps on demoied1 and demoied2 ,I get a message of "application not available".
I tried uninstalling and reinstalling the databus multiple times but with no luck.
Dear both,
our experts looked at this issue and cannot really tell how to solve you issue from the pictures.
Please be so kind to open a support request: https://support.industry.siemens.com/cs/my/src?lc=en-WW
Hopefully, you will be able to work with databus and connectors, soon!
