AutoRemote AutoRemote doesn't work in VirtualBox Android VM

I can't get AutoRemote for Android work properly in VirtualBox Android 9 virtual machine. It works for a while (a couple of minutes at most I think) but then it somehow unregister at the server and it becomes impossible to send messages to AutoRemote. When testing on http://autoremotejoaomgcd.appspot.com/ I get the error message NotRegistered. If I use the "Repair AutoRemote URL" function I can often receive messages for a short while and then it stops working again.

Is there some special configuration needed to get AutoRemote work in a virtual machine? Like firewall configuration etc?

Log file attached.

 

After rebooting the Android VM I got two Licensing messages "Licensed" followed by "Licensed Old Key" in the log.

 

Ok, thanks for your reply.
I ended up using an SSH server instead to communicate with the virtual machine
