It is possible to have 2 cloudrons under the same domain.tld ?
The main domain needs to be different, in order for the dashboard to have a unique URL for each Cloudron (the my.domain.com). It could however be a subdomain for one of the machines. And you could afterwards add the main domain to the second machine, in order to install apps on it too.
For example, you could haveMachine 1 with main domain domain.com, management dashboard on my.domain.com, and apps on app1.domain.com, app2.domain.com Machine 2 with main domain machine2.domain.com, management dashboard on my.machine2.domain.com, and apps on app3.domain.com, app4.domain.com
