git is hanging on clone. I am runnig (cygwin) git 2.8.3 on IIS7 (windows server 2012 R2). Where can I start to perform additional debugging? Selected items I have read, but they did not help: http://unix.stackexchange.com/questions/98959/git-upload-pack-hangs-indefinitely https://sparethought.wordpress.com/2012/12/06/setting-git-to-work-behind-ntlm-authenticated-proxy-cntlm-to-the-rescue/ https://sourceforge.net/p/cntlm/bugs/24/ invocation of the clone: jpyeron.adm@SERVER /tmp $ GIT_TRACE=1 GIT_CURL_VERBOSE=true git clone http://SERVER.domain.com/git/test.git 01:23:37.020476 git.c:350 trace: built-in: git 'clone' 'http://SERVER.domain.com/git/test.git' Cloning into 'test'... 01:23:37.206046 run-command.c:336 trace: run_command: 'git-remote-http' 'origin' 'http://SERVER.domain.com/git/test.git' * STATE: INIT => CONNECT handle 0x60009a140; line 1397 (connection #-5000) * Couldn't find host SERVER.domain.com in the .netrc file; using defaults * Added connection 0.
