I've been developing a flutter app in Android studio for sometime now. And I created the backend using pycharm and django.

What I've done until now:

• I can access jprq site from any browser with no issues. with the url from terminal. (JPRQ works in browser)
• I can't access the same jprq site from flutter, not matter how I change the url from terminal (Tried http://, https://, name.jprq.live:80//, etc). (Changing url doesn't work.)
• Finally I tried accessing other sites from the same flutter methods (from dart pub: http.get(), dio.get()) and I can access them. Like I do get a http response. (Flutter methods do access other sites with no issues.)
• The debugger doesn't register any request when I try accessing it from flutter but it does register a request when I access it from a browser.
• The error I get in my flutter terminal is 400 Bad request.
• I've checked flutter docs there is nothing there that gives me a clue.
• I tried connecting my server in a different network and my app (which is now in my phone) in a different network. Still the same error when I request it from http.get() or dio.get()

I do not understand what all of these means it is quite frankley very very confusing.
Can someone help asap, I need to complete this project soon.
