The Nucleus is essentially a small computer. If it’s out of warranty and it’s just the connector, you could take it to a computer-repair shop nearby and see if they can change the connector for a new one. There may be a removable network card that can be replaced with a new one. Though more wasteful than changing an RJ-45 connector, it will take less labor, so possibly be less expensive.
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,
