Thank you for your message.
Glad to hear you've figured out the issue! Yes, perhaps it might be caused by the Oracle Virtualbox software as a virtual machine usually can be configured to have its own IP address, different from the IP address of the host system. Please do refer to the Oracle Virtualbox support or user guides. Remote Utilities only generates an Internet-ID code when Internet-ID connection
is used and uses the IP address assigned to the Host machine when Direct connection
Please feel free to let us know if there are any updates on the issue or if you have other questions.
