I created a new List Search APP following the instructions by https://www.youtube.com/watch?v=SBqZ3_Dka8c Everything seems to go perfect and even the APP can be loaded into TEAMS. But when opening the APP I receive an error 'Unable to reach app. Please try again.' I have no idea what is going wrong however the log file tells me the List Search name already exists and can not deploy it. But how can it be because the APP is available? I attached some screen dumps of the APP configuration, the outcome to attach lists from sharepoint and the error message.
