Download failed

There was an error when I downloaded the source code, what is the reason and how to solve it?

$ git clone --recurse-submodules https://github.com/Dafang-Hacks/Main.git        
Cloning into 'Main'...

I tried it many times, and it was this mistake.

I think this is more a git error:
