Web - Server

Hello hackers,

I am stuck in this challenge, I think that I have found the good method to solve it but my key is never accepted.
I think that it is because I am receiving strange tokens in auth page. I have result "Hello role\r\n\r\n" in auth page, the \r\n\r\n seems strange to me
Is it normal?

Thanks you

that means that you posted "role\r\n\r\n" as your username value
