Hello All I have two node red instances, after upgrading the modbus node to the latest version, i got the this error "FSM Reset On State {"value":"failed","actions":,"changed":true}" albeit with the same configuration and hardware it works in the modbus V4.1.3 Any sugestion?

for now I manage to downgrade the version ...

same issue here, anyone fix this?!

Has an issue been posted against the node on GitHub?

@gdallaire have you checked to see whether an issue has been raised against the node? There is no point telling us about it here, it is the node author that needs to do something about it.
