Cannot connect to the PLC

[CipDoesCisco]

Good afternoon,

I've set up everything according to your 2nd video and the system works up to a point.

What works: -the Unity UI plant page -the HMI page -the VMs.

The part that doesn't work is the PLC. I'm getting a EADDRINUSE for port 8080 when running the sudo nodejs server.js command.

I suppose it has something to do with port 8080, but there's nothing else running in VirtualBox.

I'm having the same issue. Did you manage to fix it?

It might be due to the DHCP server configuration.

The VMs have static IPs, which could be causing a conflict with the adapter pools.

Everything is working except for the OpenPLC server. When I run the command sudo nodejs server.js, it shows the same message as yours.
