Unable to authenticate when creating upstream branch using git-svn

Question

I am unable to use git-svn to create a branch on an svn server, using the git svn branch <branchname> command on windows using either git-bash, cygwin or git extensions.

I would like some guidance/suggestions on how to diagnose and debug this issue.

The output on git-bash and cygwin:

$ git svn branch upstream-branch-name
Copying https://***redacted*** at r132578 to https://***redacted***/branches/upstream-branch-name...
Can't create session: Unable to connect to a repository at URL 'https://***redacted***': No more credentials or we tried too many times.
Authentication failed at C:\Program Files\Git\mingw64/libexec/git-core\git-svn line 1199.

For information, I have cygwin, and TortoiseSVN installed as svn providers on my system.

EDIT1: Additionally, I am able to do git svn rebase and git svn dcommit without any error

Answer 1

Check first your Git version in your Cygwin environment.
I mentioned here a Git 2.13+ (March 2017) should be more robust when it comes to authentication issue.

For testing, try (as mentioned here ) to uninstall TortoiseSVN and see if the git svn branch does work then.
