Hi. My Sensor can not send data to the apis like the community or madavi. I run this sensor for about 2 years now and all works fine for all this time. For about the last 4 month it works only for some minutes or hours a day,if any. The sensor is reachable from wlan, as well as from the web, it sends data to my own server, but no data are send to other servers. Nothing has been changed here. What can be the reason?
