Description of Issue

I have been using the Roon Optimised Core Kit on my Intel NUC for a few days now, the Core Kit is running but Roon ARC does not connect. this was still possible when I used my 1621xs Synology as a Roon server, I forwarded the port 55000 on the NUC in the router and logged in again to my Roon account, but all this is of no use Roon ARC does not connect.

Please fill out the questions from the posting template, it’s impossible to help if we have to guess your setup. I have copied the questions from ARC: Port Forwarding Help which also include the network setup

Have you removed the old ARC routing rule for the (presumably now defunc) synology Roon server. If not, have you got duplicate routing entries for port 55000 routing to two different servers?

If this is the case, you will need to do one of:

1. Remove the original port forwarding rule.
2. Change the port number in both the Roon Server → Settings → ARC page and the Router port forwarding rule to something other than 55000 - say 55001.
