Hi All,

I have installed Openstack on Solaris 11.2 in virualbox. Earlier i was able to access the horizon dashboard with glance user but now i am getting error on the browser. Below is the part of error. If you need complete log i can post the same.

If anyone looks at the answer later then here is exactly what i tried. Reset the password of users. But that didn't helped and i was getting same error. Tried in different browser (IE) earlier was mozilla, but that also didn't helped. Finally rebooted the VM and and re-opened browsers, it's working now.

PS: I hate when things work only after reboots. If anybody know a service whose restart may have also resolved this issue than please let me know.
