Hi @Keith_Gierman ----- Thank you for the report and sharing your feedback with us.
I must admit that I am bit foggy on what the error is here. Based on the above it sounds like you are unable to control you core from a remote device, is this correct? If so, I would recommend confirming that there are no active firewalls on your system OR antivirus applications (with build 269 installed).
Furthermore, can you please expand on your setup description using this link as guide.
