Problem Initializing Submodules

Hi, I’m having a problem building MissionPlanner in Visual Studios for the first time. I have followed the guide, but the submodules don’t seem to be initializing. I get these errors when I try

git submodule update --init --recursive

"Cloning into ‘C:/Users/Eric Work/Documents/MissionPlanner/ExtLibs/mono/external/api-doc-tools’…
fatal: unable to connect to github.com:

I was able to initialize the mono submodule, but not any of the submodules inside of it.

Any help would be much appreciated. Thanks!

make sure that your git uses https: instead of git:
make this config change

git config --global url."https://".insteadOf git://

Thanks a bunch! That did the trick.
