The ServicePointManager does not support proxies with the net4bsl.bsl.co.uk scheme

Question

I get this error when trying to sync a team project on team foundation serer in visual studio 2017 at work

Git failed with a fatal error.

NotSupportedException encountered.

   The ServicePointManager does not support proxies with the net4bsl.bsl.co.uk scheme.

cannot spawn /c/program files (x86)/microsoft visual studio/2017/community/common7/ide/commonextensions/microsoft/teamfoundation/team explorer/Git/mingw32/libexec/git-core/git-askpass.exe: No such file or directory

could not read Username for 'https://ams-british-steel.visualstudio.com': terminal prompts disabled

This is what I have configred as my proxy

git config --global http.proxy net4bsl.bsl.co.uk:8080

Any ideas?

Answer 1

You're not entering a valid URI scheme, such as http://. Try putting http:// at the front of the proxy address.

Answer 2

Check if you have set the Windows environment variables HTTP_PROXY and HTTPS_PROXY. If they are set, make sure the schema (http and https) is written there. If you modify that variables restart the terminal and try again.

I had the same issue and I solved it in that way.
