Error while trying to connect with Real robot

[Adarsh3559]

Hello @matteolucchi, @friedemannzindler ,

I am trying to connect with real robot and trying to see if it works but I am facing this error.

InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
status = StatusCode.UNAVAILABLE
details = "failed to connect to all addresses"
debug_error_string = "{"created":"@1662562119.121773777","description":"Failed to pick subchannel","file":"src/core/ext/filters/client_channel/client_channel.cc","file_line":3186,"referenced_errors":[{"created":"@1662562119.121773359","description":"failed to connect to all addresses","file":"src/core/lib/transport/error_utils.cc","file_line":146,"grpc_status":14}]}"

To let you know i am using Oracle Virtual machine running the whole setup Ubuntu and ROS noetic, it this error due to Oracle Virtual Machine communication or it has nothing to do with virtual machine,

Also I would like to ask will it work if i try to do the same on the NVidia jetson nano??

I would be really glad if you can answer or provide some hint on this issue. As i really want to get it working

Thanks and Kind Regards,
Adarsh Sharma
