All Instrance Dissapare
Have found an bug in ADS/Role Management/ All Instances seems to vanish from the list under AMPCore, This has happen an couple of times now, Temporary fix is to restart the controller not completely Ideal.
Before Controller Restart:

After Controller Restart:

You have to share some more information. I assume this is a standalone installation? Which OS, version and so on? Any errors in the browser console (F12) while the error occurs? I never experienced that problem on a controller/target installation.
Oh my apologizes I thought I had provided enough for the basic rundown of the issue when I mean controller i basically mean AMP in general I have it as an standard standalone when i mean controller i mean that by the actual ADS instance etc Server 2022 I have no clue when it occurs but basicky each time i go to look its gone :P
This is likely related to the same issue as #764 wherein a newly deployed instance is unable to be viewed in ADS until a controller restart. There is also the issue from time to time (not that I've been able to nail it down) wherein whole Targets will be removed from the ADS "All Instances" menu when assigning role permissions.
This has been fixed in 2.5. It was an enumeration issue.
