So i had one of these bulbs for a while now worked perfectly fine never had any issues. I bought a second one which i never managed to connect to the app and get it to work. As a bonus now the first one also doesnt connect. I have tried resetting them multiple times, the DNS change to google and other stuff nothing works. I did manage to connect them through a friends phone hotspot but yeah i need to connect them to my network. Any idea on what could be wrong and how i can fix this?
