I installed DSS on a mac, OS Yosemite 10.10.15.
While starting DSS, the chrome browser open an empty page with the following text :
"Could not connect to Data Science Studio server
Please check if DSS server is running.
HTTP code: 502, type: Gateway error"
I got no firewall on. DSS have been uninstalled 3 times.
Thanks in advance for your help.
