Hello, I am dealing with RAPID variables that are overwritten by a backend program through REST API. After the mastership is given in robotstudio + the RAPID program modified + mastership released, it sometimes occurs that the backend "looses" the subscription to some variables (not all) and can no longer change their value. However, when the controller is restarted, the subscription becomes ok again and any change of the variable is detected by the backend. Are there any known issues with REST API and connection loss to PERS variables, and recovery at controller restart ?
