Hi, guys.  
I installed Opennebula 5.11 and got error with Sunstone a tab Instances-VMs.  
When I click this tab i don’t see any VMs, but a command onevm list show my VMs.  
And when I want to move from the tab Instances-VMs to other tab, my Sunstone interface doesn’t work, helps only refresh а page.  
And when i move to a Dashboard tab i see Virtual Machines blinking block.  
Where is the problem?

In the logs i see:

> ```
> Message received: LOG I 74 Command execution failed (exit code: 255): /var/lib/one/remotes/auth/server_cipher/authenticate

Hello @define  
Thanks for the feedback! Very appreciated that you have tested the beta upgrade.

We have reverted some changes in the last days, if you can update your installation again it should be fixed. Dont forget remove the browser cache after installation.  
Anyway, if you experience a similar error again, I would appreciate a screenshot of your browser console.

Best,  
Sergio
