Hi, I have problem with this issue. I have installed OpenStack Folsom succesfully by https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst I do not know why, but after few days when I want to call some command to quantum, for example quantum router-list, It is failed with [Errno 111] Connection refused. Does anybody know why it is? Thank you -- Lukáš Vízner
