Android app data doesn't upload to website

When I tried to upload profile picture or update profile data. It doesn’t work via app. But if update to website works perfectly. App can only fetch data from website easily.

It seems to issue because of cloudflare firewall or something else i’m using amzone S3 as well.

I don’t know how to resolve this, I saw many dating website using cloudflare with their android app.

Please let me know what to do do I need to create any page rule

App is not published yet.
