I just installed CloneDeploy 1.2.0 on a fresh copy of Ubuntu Server 16.04 LTS. After the installation, I attempted to access CloneDeploy web via the IP address of the computer: http://192.168.1.2/clonedeploy. After I press return, I get the error "Service Unavailable: The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later." Any ideas on how to solve this problem? Thank you!!!
