Github does not get connected and no source code is dispalyed

Hi,

I experience that when I show the doc({command}) and then choose to show the source codes, the connection to github is crashed and no code is being displayed. this happens for me very often but I also had cases where the source code could be displayed. I really did not find a systematic difference between those which show the code and those that do not. Any suggestion?

Best regards,
Afshin
