Ben with the support team here, welcome to the community, and thanks for writing in! I do want to inform you that we’ve moved your support thread over to #tinkering due to your use of a VPN within your local network.
Unfortunately, this isn’t something within the scope of Roon support. Luckily, there are many knowledgeable users within the community here who may have a similar setup and may be able to provide additional insight into your issues.
