communication error

  
please teach me!!
i installation now.
but after clickin Service Studio9.0
'There was an error contacting Host Not Found'
What is Hostname? the hostname xxx.outsystemcloud.com is't it?
Solution
Yes, that's the correct format.  Do you remember what you set as your hostname when you signed up for your cloud environment?  Maybe you made a typo when you created it?  Double-check everything.
Solution

Thank you Curt!!
The error I was resolved.
The input infomation was right.The issue was Service studid Proxy setting.
