Problem Description

Issue

I clicked “stop instance” for an application several weeks ago, and the “Stopping Instance” message now shows perpetually, and has been this way for a month. I also cannot delete the instance since I have important files in it. I cannot manage the instance at all.

Reproduction Steps

  • Clicked “stop instance”
  • tried to update instance
  • tried to update AMP

Right click the instance and hit View Logs to see what’s going on

Only issue I can see there is that you have Java 20 selected for something that needs Java 21, the rest looks fine

5

I’m aware of the issue there, but my post was to do with the instance itself being bugged or something. AMP won’t even let me manage the instance.

6

The instance looks fine, do you get any errors in the ADS’s deployment log?
