Versions of the related components and OS (frontend, hypervisors, VMs):
No VM’s yet just a frontend where I am not able to login create users etc.
Steps to reproduce:

Current results:
None
Expected results:
To be able to login to sunstone with oneadmin and do basic configuration. Add users, vcenter etc.

I have found the cause of the issue. Sunstone-server.conf session: can not be memcached or dalli-memcached. So when memory specified it works.

Hi @Stefan2,

Thanks to comment what you did to solve it. I found this on our github, that goes in a similar direction: Sinatra doesn’t know this ditty after upgrade to 5.4.12 · Issue #2069 · OpenNebula/one · GitHub

Cheers,
