ePaper Waveshare 4.2 Cloud Module with ESP32 (18525) - app connection issue

Hi, I just got the ePaper Waveshare 4.2 Cloud Module and am trying to set it up. However, I can’t get the app to upload the configurations to the module - I always get a “Configuration upload failed”. Did someone have the same issue and found a solution? I feel stuck at this point and have managed to figure out everything else.

Goal of the project: display the next meetings in a meeting room via a raspberry pi

Thank you for your help!
