I've moved this thread to the openSPOT2 forum, as you wrote in the openSPOT1 forum.
If the LED is green, then your openSPOT2 is connected to the Wi-Fi network, and also connected to the configured server.
If you mean that you can't open the web interface of your openSPOT2, then:
- Make sure you use
https://sharkrf.link/
- If it still does not open, place the openSPOT2 closer to the Wi-Fi AP
- Make sure that your browser device (phone/tablet/computer) is connected to the exact same Wi-Fi network as you've configured for the openSPOT2
- Make sure that Wi-Fi client isolation is turned off in your Wi-Fi router's configuration
