Host name conflict
<!-- You must use the issue template below when submitting a support request -->

Problem Description:
I keep getting a host name conflict with multiple instances of home bridge. I moved one of the two to another raspberry pi because I thought that may have been the issue, but I still have the same issue.

**Logs:**
