Trouble shooting

Would like to see more information from in app as to what’s happening. Flame loss during calibration?? Why, where do I go to look. Yeah it says call my contractor he is not available for many days.
Update: I made a couple of phone calls and was able to talk to a viessmann regional representative he was a big help and was able to get my boiler operating. I will be working on the fine tuning to improve the operation of my boiler.
