Changed Wifi and updated firmware, device online, signal good still not working!?!?

Hi everybody,I changed my Wifi Name and Login so I reseted my Doorbell with the orange button and change with the app the Wifi for my Doorbell. Everything looked good, I got the message that the Firemware need to be updated and I did this as well. Same thing for my attached Door Chime. Both are now visible in my Mobile app, both online and both healthy.My Rssi Signal is -45 and I got the message that the singal is good. I can configure and adjust and the Doorbell seems saving everything well. HOW EVER, when I press the doorbell button I can hear the Ring in my Ring Device but never in the door chime or my phone! Also the even list is not updating and it looks the Doorbell cant cominucate with the server from Ring. Since I can configure and get even the device health etc. all seems fine from my side internal.Is it possible that my Router dont allow the Doorbell some Port etc? How the Doorbell connects with the Internet and Chime? I tried all I imagine, switched off and on, loggin logout several times etc. What can I do to make my Doorbell work again? Before the Wifi change and update of the firmware all was working well. But since I get the message that both devices are online and healthy I am a little bit out of ideas.thx in advance,Oliver
