Disconnected from server

[Cizkolade]

I have a problem when i log into WoW Classic and type my Account Name and Password. Im getting the "disconnected from server" message up. i have an idea about why.
When i try logging in, it doesnt say "Nostalrius Begins" in the bottom right corner. it says "Test Realm - IsVV2"
How do i change it to Nostalrius Begins without logging in?
