Roon Nucleus repairs

I have a 3 year old Roon Nucleus.  The ethernet port no longer grips the ethernet cable; the cable falls out with minimal movement.  Its not a cable issue as I have tried several different cables; all with the same results.  I contacted Roon but have not had any meaningful response.  I get the feeling that they have no support for the hardware they sell.  My dealer is no longer available to help out.  Has anyone had any luck getting a nucleus repaired?  Or is it time for a new server.  Thanks,
