The VRM connection may well be trying to use your ethernet connection to access the internet, which of course does not have internet being connected to the PV inverter.
This may help, but note, it is not something I have experience with.
Having a local Ethernet network while using WiFi for the internet connection is also possible. To achieve that, Manual IP configuration is required:
• Set the Ethernet gateway to 0.0.0.0
• Set the WiFi gateway to a valid address (ask your network administrator for the correct gateway address)
Important
Connection priority is based solely on network interface availability, not on whether the connection provides actual internet access. The device does not verify connectivity to the internet when selecting an interface.
There is also a thread about this in the beta testing.
