Hi, Horizon use keystone to authenticate. devstack run all the service in a screen session. When you reboot, this screen session is stopped and all the services with it. Running "rejoin-stack.sh" relaunch the screen session and the associated services (notably keystone). Without this script, no keystone => no auth. So what you do is correct (running the script, and login in horizon after).
