How do I remove these strange blue lines when the sun is setting in my game

I have recently been trying to create a day/night cycle in my game and I’m getting an incredibly strange issue where these blue lines are showing up in my sky after the sun sets. I have messed with all the settings on the directional light and I can’t find anything to make it go away so I’m not sure what to do.

I figured out that the issue is tied to atmosphere thickness in the sky box settings. Setting it too 0 got rid of the issue for me
