The message in browser,

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

I think the connection to Github has no problem.

version

grip -V
Grip 4.4.0

I have the same problem, seems related to https://developer.github.com/changes/2018-02-01-weak-crypto-removal-notice/

So Github just turned off the TLS1.0 and only allows TLS1.2, I fixed the issue with the openssl upgrade and python reinstallation.

brew update
brew install openssl

Then openssl version should be 1.0.x

brew update
brew install pyenv
echo 'eval "$(pyenv init -)"' >> .zshrc
source .zshrc
pyenv install 3.5.2
pyenv global 3.5.2

python --version 
python -c 'import ssl; print ssl.OPENSSL_VERSION'

After that, you can see python is using openssl 1.0.x, and if you reinstall grip everything should be good.
