When I try to login, it says unknown account and ask me to create a new account. [URGENT]

I just created a new sync account on my desktop, but when I logged on my laptop, the prompt asks me to create a new account. I am sure that my user name and password are right. Both devices have Firefox 51.0.1 Laptop is Windows 10 and desktop is Windows 7.

I had this problem since last year, but only recently did I urgently need to since my bookmarks and passwords.

Thanks

I called for more help.
