<div dir="ltr">Hi Yipei,<div><br></div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>BR</div><div>Zhiyuan</div></div><div class="gmail_extra"><br><div
