Nostalrius Begins - Quality wow vanilla realm (1.12)

I start downloading Nostalrius-WoW-Classic.zip And at 18 half way through 19 it says Temporary error, Every time it gets there, And I hope someone here knows how to help me by pass this.

And after I refreshed it and tried to download it once more it goes to 16% says "Temporary error" and Goes back to 15%
