Delay and reason

Hey guys. I have been having some problems. Here below is an example of my problem and why my cracker will be delayed.



Without proxy and trying in browser:
Successful login

With proxy and trying in browser:
Bad login

Without proxy and trying in my cracker:
Successful login

With proxy and trying in my cracker:
Bad login


I tried multiple proxies and solutions. I tried a vpn and that was successful but there isn't millions of vpns. If you got input on my problem then go ahead.

So it's a proxy issue?
