Change hostname from server

Hi, i had two servers. Last week, i change the applications from one server to another.
In Argo Tunnel, i deleted the DNS entry and destroy the old server.
In this new server, i had a hostname new-apps, but i change to apps, when i use the command

cloudflared tunnel login

the certificate is created and downloaded, but the DNS entry is not created.
In the logs, i see this error:

Serve tunnel error: There is already an active tunnel for "hostname". To distribute requests between multiple origins, use Cloudflare Load Balancer. Existing tunnels not using the Load Balancer will need to be registered again

“hostname” is a example for my host.

What can I do? I’ve tried to reinstall, use another hostname and nothing has changed.
