From the remote host I had no problem deleting the task.

We are configuring the first start, everything was correct, but for network reasons, the IPs of the hosts had to be changed.
Before changing the IPs I am trying to delete the tasks and disconnect the replication. I can not disconnect the second host because it indicates that there is a task, which is the one I can not delete.

I have also tried to reset the configuration data from the console, but it doesn't work either.

The only option I have left is to reinstall all the software.
