Visual Studio connect to GIT server

Question

we get the following error trying to connect to a git server inside our company network. proxy configuration to config file was added and works. same errors appears when i try to establish a connection to github.com

error: libgit2. Category = Net (Error). Response status code does not indicate success: 417 (Expectation Failed)

Answer 1

finally found the solution on my own. Editing the “devenv.exe.config” file and adding "expect100Continue" parameter solves the problem.

<settings>
<ipv6 enabled="true"/>
<servicePointManager expect100Continue="false"/>          
</settings>

connecting to github and our local gitserver work fine now.
