Hi, Yipei, You can use “ps aux |grep python” to see processes started for OpenStack, and make sure services started successfully. And use “netstat -tulpn | grep :9696” to see which process is listening this port. Maybe your Neutron API has not started successfully.

The results also indicate that Failed to connect to 127.0.0.1 port 9696: Connection refused. Unlike the error mentioned in last mail, I still cannot find any processor is listening on port 9696 after running "rejoin-stack.sh". Best regards, Yipei On Mon, Feb 22, 2016 at 11:45 AM, Vega Cai <luckyveg...@gmail.com<mailto:luckyveg...@gmail.com>> wrote: Hi Yipei, One reason for that error is that the API service is down. You can run "rejoin-stack.sh" under your DevStack folder to enter the "screen" console of DevStack, to check if services are running well. If you are not familiar with "screen", which is a window manager for Linux, you can do a brief search. One more thing you can try, change the IP address to 127.0.0.1 and issue the request in the machine hosting the services to see if there is still "Connection refused" error.
