First start gives error "cannot decode message v1.Multihost from JSON: undefined "

[obones]

Hello,

I just downloaded and installed the latest Win64 release and while the setup went just fine till the end, I have an issue with the first screen that comes up:

I'm trying to give the instance its id but whichever value I set, I always get an error toaster when I press "Save" with the following message:

Operation error: : cannot decode message v1.Multihost from JSON: undefined

What have I missed?

Somehow the search in issue for the exact error message did not turn up this issue: #853
I'll follow this ticket then
