I have been using an application on TTN for the past year without any issues. But two days ago, All my 72 nodes stopped transmitting data at almost the same time (5/23/2019 22:47:45). I have tried to register new devices on the same application but they don’t work.
However, when I register the same device in a different application, they start working.
The only difference between the applications is the handler.
The working application is using ttn-handler-asia-se, and the not working application is using ttn-handler-eu. Would this be the cause?
The image below shows an overview of the not working application.
It’s worth mentioning, that I made a new application using ttn-handler-eu. It is not working either.
Would it be possible to change my handler without having my devices removed?
I am using ABP. therefore, I need to set the DEVADDR.
