The command is written incorrectly, followed by the task name

tiup dmctl --master-addr 192.168.111.111:8261 stop-task task-name

:joy::joy: Writing the task’s file name is also acceptable

Okay, my bad, I’m used to using the task name. Try changing dmctl to version 5.4. I noticed that dm is version 5.4 and ctl is version 6.1, which should be causing the version incompatibility.

Yes, the dmctl version issue. I installed the latest version by default, but after switching back to the same version as dm, it worked. Thanks, expert.
