JIAOYUE YLXD02YL connection time out

Hi I recently purchased a JIAOYUE YLXD02YL and I can’t connect to mi home app or the yeelight app. Tried the things that you mentioned in this forum but still nothing works. I tried to log8n with the dingychen@yeelink.net but the password won’t work. Please help to resolve this issue. The router has dns in its settings
