DSM error

[typer77]

I have been getting this error:

 

You have logged in and out of DSM using another web browser, or DiskStation has been restarted. Please log in to DSM again.

 

After googling, I still can't find the solution. Has anyone experienced this?

 

this also leads me to a 2nd question:

Since I have another machine laying around, can I set up MS server Hyper-V on the 2nd host and run a VM redundancy?

 

thank you for your input.
