I have the same problem, or not... I cant configure the datalogger more then step 3, dont connect to internet. My problem was the internet router, i change it with a new one, i must reuse the old one in parallel with the new one (mesh) connection. I add the logger from the WEB page not with app, and after few seconds apear in app to. I connect the old internet repeater and press the doggler key one time. After i repeat in app the stept for doggler connection with the same problem, i connect to doggler hospot and go to settings and put the old wifi repeater and the password. After the apply and reset my doggler connect to the internet normally like in past. 2 days i must to search on internet and make all steps (doggler batery remove, etc)
