New wifi / lost connection

1

I have changed my Wi-Fi provider, and as a result, my fine dust sensor (SDS011) is no longer visible on the map. When I try to reconfigure it, I select the new Wi-Fi network on the configuration page and click ‘Save’, but I always get the same error message: This site can’t be reached. It took too long to respond to 192.168.4.1.
Automatic connection to the home network is disabled.

Chip ID is: 3131782
API IDs are: 75661/75662

After the restart the IP it’s normal that the IP is not reachable. This IP is only accessible when you are directly connected to the sensor hotspot (which is not active when the sensor is connected to your home network).
