Assuming you know this doesnt work anymore?

Fatal error: Uncaught InstagramScraper\Exception\InstagramException: Response code is 401: Unauthorized.Something went wrong. Please report issue.

regardless of username/auth etc..

looks like meta had more session stuff in the mix that breaks this

If you just need to retrieve IG profile info, and last 12 posts, check https://github.com/skmachine/instagram-php-scraper - it does not require your IG auth details and uses cloud proxies (requires subscription). This lib won't help if you need followers or emails.

what about if I just want to get a post and its comments? nothing seems to work as of now
