Click the Cancel instance button in Operate, and the rotating circle has been displayed for several hours.
I tried cancel from zbctl, but the situation has not improved, ActivateJobs can still see all the jobs.
Using Kubenetes 1.18.0, helm: zeebe-full, default settings.
Docker image camunda/zeebe:0.23.4
Hi @BigeYoung,
first, welcome to the Zeebe community 
In order to analyze and reproduce the behavior, you need to provide more information.
If the system is under load then Operate may be a bit behind importing the data from Zeebe. So, it can take a while to see the updates.
Best regards.

If the jobs are still activating, then the process has not been cancelled.
There are two channels for Operate: one is the Read channel, which is a connection to ElasticSearch. It sounds like this is working fine.
The other is the Write (Command) channel. For this, Operate needs to access the gRPC API on the Zeebe cluster gateway. If this connection is not working, you would see this behaviour.

Hi, thanks for your reply. I click the cancel button a week ago, but they are still running now.
Before this, I also encountered this problem, so I used helm to completely reinstall the zeebe server, but after that I still could not delete any workflow instances.
The gprc gateway is working well, I can create workflow instance, publish message, and more.
Oh, I see a long error log when I type kubectl logs zeebe-zeebe-0:
