I have a problem with viper06HN in non isolated flyback converter , I think that happens due to self biasing (the chip get its power from drain voltage not the aux winding) , this happens at startup and after that the chip power from the Aux winding , but is there a reason can affect this process ?
attached my schematic

There is no problem when design SMPS with self biasing.
