It would help to know what operating system, computer and virtual machine you are using

I’m using Ubuntu 20.04. 3 andVirtualBox 6.1.26

Have you tried going to the Nomad in your virtual machine’s browser? http://localhost:4646
Your device might be there

yes, but it says that it is unable to connect

I don’t know. I do know that the developers do check the posts here, so it is likely they will or are already working on a fix for this problem.
