Provide a description that is worded well enough to be understood

I am still able to download Instagram ‘reels’ just fine, but suddenly cannot download any ‘stories’ as of early morning on October 5th. It says I need to log in when I am already logged in to the same account on Chrome browser. I have been doing this exact same thing daily for the last several months with no problem (downloading ‘stories’ from multiple users).

I’ve seen the notes about how using yt-dlp with Instagram is risky, but somehow I’ve never had an Instagram account banned due to using yt-dlp.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below
