works for me when changing in .git/config

[submodule "static"]
    url = https://github.com/sympy/sympy-web-static.git

Yeah, sympy.org had the same problem. I'm not sure why this happens now.

The following change to .git/config also seems to fix this issue.

[submodule "static"]
    url = git://github.com/sympy/sympy-web-static.git
