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

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?
