Hi,

Thanks for reaching out! The error says You must have at least one enabled healthy machine in the environment before deployment can proceed. which means that at the time of deploying that release, you did not have a healthy machine on the target environment. You need to have at least one machine registered on the target environment that’s not disabled or having connection issues at the time of the deployment, or else you’ll get that error.

As soon as that error happens, I recommend you to check your Environments page in the Octopus web portal and check what is going on with your Tentacles.

Hope that helps with your troubleshooting.
