Hi @Anjan_Ghosh,

Thank you for your patience. I’ve split your post into a dedicated topic thread we can troubleshoot directly.

This entry - ConflictinMappingEntry - in the above diagnostic suggests that the UPnP addressing stack is working, but there’s another software program reserving the port Roon has attempted to configure for ARC.

In Roon → Settings → ARC and any related port forwarding rules you have manually created in your router settings, try augmenting the port assigning by a few hundred or thousand. For instance, if the port is currently assigned as 55000, try 56000 instead.

Please let us know if this helps. Thanks!
