Issue with Yeelight strip

So I recently bought a Yeelight led strip and I was really happy, it worked really well until I disconnected it. After a while I reconnected and then no way to get it working. Tried change the socket, uninstall-reinstall the yeelight app, tried different apps on android ( EMUI 8.0 android 8.0 ) I reset it twice, nothing to do. The little led on the controller shows constantly blue. But the real problem is thant on the yeelight app the led seems connected. It’s just like it’s not responding to my order. On the app it says that the strip is on but it isn’t actually.

Do someone has any solution to this ? Thanks !

ok I found a solution.just the between the lighstrip itself and the controller who had a little prob fixed.
