hello all
i have now figure it out how to fix this issue, i will give you the solutiont, if the administrator thinks its not really an issue please delete this whole topic.
turns out i had to go to smartthings gui and delete the smartapp from "my smartapps tab", i was just deleting the switch and the smarthome app from smarthings, but for some reason the smartapp just kept the old token and not the new one when i add my computer again in the triggercmg website
i figure this out by consulting live logging on the smartthings gui.
its all working now, thanks 🙂
