Hi,

I try to create a pipeline project, but get always these errors:

1st try: using "real" hostname with

same result as JENKINS-35565 (connection refused)

2nd try: using localhost/127.0.0.1 (I tried both, same result)

first with "Credentials" set to "empty"

theres simply no connection attempt inside /var/log/auth.log

It seems that it fully ignores ~/.ssh/config (int the correct home of the jenkins user), since it does not use the private key specified there.

If I specify a private key inside the "credentials" (i.e use private key from jenkins-master home), same error occurs.

it seems the branch indexing simply ignores every credential provider or standard ssh/git behaviour.
