Hi , i recently got yeelight white bulb(YLDP01L) but i can’t connect it .My phone recognizes the lamp but i get all the time “connection timed out”.I changed the server from germany to europe to mainland china to singapore ,nothing.I live in Greece.I installed on my phone yeelight app ,Mi app nothing .I changed my router settings to static and DNS nothing.Ichecked my router is on 2,4GHz .Is there anyway to work or i spent my money without meaning ???and i should go to philips hue??Thank you for the answer.
