I noted another error that I thought might be significant:

[OpcUaConnection] Subscription transfer failed, id=1, status=StatusCode{name=Bad\_ServiceUnsupported, value-0x800B0000, quality=bad}

This seems similar to an error in this post. [OPC-UA Server Connections and Tag Issues](http://forum.inductiveautomation.com/t/opc-ua-server-connections-and-tag-issues/22206/11). Any relation?
