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/

[xavierchow]

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.

Thanks a lot for this hint!

Important to add: This won't work with the Homebrew version because the Homebrew version uses an old Python (at least for me). So maybe, the Homebrew version needs an update?

[cunninghamzac]

I couldn't get this to work with Homebrew either. I ended up uninstalling grip in Homebrew and re-installing it with pip after I did the other steps

brew update
brew install openssl

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

Thanks @cunninghamzac! Uninstalling it via Homebrew and using pip install grip worked for me, too.

@peterfication, Homebrew now uses 3.x as the default python.

[joeyespo]

Yes, this is due to GitHub shutting off weak TLS.

Thanks for chiming in, @shirohana, @xavierchow, @cunninghamzac ❤️

[joeyespo]

Actually, while I'm releasing new versions, I added an except block in v1.5.2 pointing people here if they happen to hit this error (f015871c4af7b8a956ed41c9b6bfdd1e6ad468cb). Can anyone still experiencing this confirm it worked / add anything missing? Thanks again!

@joeyespo I got your error, there is a spelling mistake in the error message though. I made a pull request https://github.com/joeyespo/grip/pull/266
