Hello. I have made some network changes for ethernet and I cannot reach my nucleus anymore. Not on my phone, not on mybrowser or windows application.
You have to find out what you changed and where they affect connectivity.
Did you change wires, moved a device etc.
Can you get online from any device connected with eg. wifi?
Do they get IP addresses (check in settings on the device).
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
What kind of network changes did you make?
