Instagram started blocking aggressively websites and platforms from scraping their pages. This came after HYP3R violated Instagram's privacy policy.

What is a workaround?

Using a high-quality proxy is one of the best ways to avoid this. Here is how you do it:
  1. Choose a high-quality proxy provider. One of the best that I came across is Blazing SEO Proxies.
  2. After signing up, choose US-based proxies. They are more reliable. Also, make sure to choose dedicated IPs. You do not want to share your IP with others.
  3. They will provide you with the proxies you ordered as soon as you process the payment.
  4. Add your proxies, ports and credentials in your platform.
  5. You are done.
Hope this help.
