Chime pro wont reconnect after offline

My chime pro and doorbell 2 stopped working some days ago. I have managed to reconnect and get the doorbell working but the chime PRO wont connect to my wifi no matter what i do. The wifi is 100% in the area and i have tried everything from restarting router to resetting the chime PRO and disconnect it from outlet, Held button for 5 sec (one option) and 15 sec (other option).. everything but it wont connect on the last part = wifi…. I really Need helpI have 3 wifi (default, children and guest) and it can connect to the childrens wifi but not the default as usual and the one it been connected to for over a year? All same settings on all those wifi’s only diff passwords.I use WPA-2 and UBIQUITI DreamMachine as router and AP’s to extend wifi.
