Error connecting to PLC: [object Object]

Hi guys,

Im coming across this new error message Ive never seen before -

Error connecting to PLC: [object Object]

Im trying to connect a Pi to modbus server. I made the modbus server on S7 (Im aware of the S7 node however its not usable here due to other reasons beyond the question at hand)

I made the node red flows on my laptop which can read it perfectly fine, I copied over the same settings to my PI and it just wont connect ( the read node is stuck on initialize )

Any ideas forward?
