You won't believe it, my friend. I had already tried everything yesterday and everything was fine. I couldn't find the problem until I read your answer mentioning production and development. It made me go to the button, put the DLT into development and then production again right away. To my surprise, the problem of the cluster not shutting down stopped. The funny thing is that it was in production, and only that DLT had a problem. The rest of the others were working normally. I honestly don't know what happened, but it was solved. Thank you very much for your help and answers.
