@jcdick1 I run opnsense on xcp-ng personally as well and use their packaged tools without issue, the only time I've gotten this behavior is when I hot-added interfaces and it changed the order of interfaces. If that's not it, I'm really not sure what would be causing this
One last thing you can try in case it's a weird cash issue is (inside XOA) go to settings > servers, click the green connected button next to your xcp-ng server to disconnect it from xoa - then wait a couple seconds and click it again to reconnect it
