500 Internal Server Error

[foxman209]

when I save the file, the browser show me :
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.
My config is:

let vim_markdown_preview_github=1
let vim_markdown_preview_toggle=2
let vim_markdown_preview_browser='Google Chrome'

I ran into this too, it worked for a while. It might be that we've been rate limited since grip contacts the github API. This is my guess.

I got this error when I was disconnected from the internet. I guess @drmason13 is likely right about the API contact. Reconnecting made it go away.
