URLError: [Errno 10054] An existing connection was forcibly closed by the remote host
after trying to push to a cloned repository, the problem is probably your URL (even though it seems to connect and authenticate fine). For some reason certain files are inaccessible (In git you'd get: error: The requested URL returned error: 403 Forbidden while accessing https://github.com/username/project.git/info/refs). To fix this you should add your username to the url:
git+https://username@github.com/username/project.git
This would work under git, BUT, this doesn't work with hggit for some reason. It gives:
URLError: [Errno 11003] getaddrinfo failed
That means our only alternative is to use SSH, and with github, you're required to use public/private keys. These need to be generated and can be set here in github. In windows/putty, here's good info on generating them. Then they can be used by default in mercurial by adding an entry in the mercurial config files:
[ui]
ssh = tortoiseplink.exe -ssh -i "C:\Users\UserName\mykey.ppk"
Hopefully you should now be able to connect using SSH and push changes to the repo. The whole thing falls under the category of "should be easy but isn't."
