We have a running Folsom Openstack cluster running for the past month with no issues. Today, unexpectedly, I can no longer log into the dashboard. I get the following error page on my browser (below) when trying to hit the dashboard URL. I've also included the apache error.log file. There aren't any errors reported in the nova.log

Any ideas what could be the issue? I've restarted all nova services and rebooted the server. I'm still seeing the same error.

Thanks, Dave

This is the apache error.log I'm seeing. No errors in nova.log.

I suspect the issue with cokies and cache. Can you try clearing them ? Also can you try with another browser or different system ?
