I’ve recently moved to a new apartment with a new modem which my version 2 led color bulbs have trouble connecting with. Other devices have no trouble connecting. The bulbs have been reset and I’ve tried setting the DNS server to 188.8.131.52 and 184.108.40.206 with no succes. After hitting 50% progress slows down and at 100% I keep getting the error “Connection timed out”. The modem I’m working with is a draytek vigor2132F and I’ve set my yeelight app to the (suggested) German server (ID 1917653912). Any advice would be most welcome.
