I installed it twice and it pop out error in the same place.
"error : Failed to destroy network default. Requested operation is not valid:network 'default' is not active"
"connection error (HTTPConnectionPool(host='127.0.0.1',port=8773): Read time out"
"Error executing action 'run' on resource 'ruby_block[Install Service Image]'"
I set static ip address for the computer and using cents 7.2.
