Your awning has probably moved in the awning rail on the trailer. Unroll the awning, slide the awning in the rail on the trailer toward the awning arm that is not going in all the way approx. 1", then roll back up, what that does is center the awning on the roller to the rail. After it closes up properly, put a screw in each end of the awning rail to secure and hold in place...
