Hi,

I am new to git so please excuse if I'm using any wrong terminology here.

I downloaded the appliance (https://www.turnkeylinux.org/gitlab) and deployed it on esxi. everything installed correctly and i can access the git server from other computers.

I have a development server (on the same vm host as the git appliance) and I am trying to push the files from the development server to the git server, so the master is the development server.

I setup a group and then setup a project.

On the dev server (ubuntu 14.04) after i installed git, i run the following command in the directory i want to push:

cd signup <- that's the folder name
git init
git remote add origin http://abc.mydomain.com/groupname/signup.git
git add .
git commit -m "initial push"

so far everything works without a problem.

When i enter the following command:
git push -u origin master
I am asked for 
Username for 'http://abc.mydomain.com' 
and i enter gitlab-admin (which is the administrator username)

I am then asked for a password and after i enter the password i get the following error:
error: Cannot access URL http://abc.mydomain.com/groupname/signup.git/, return code 22
fatal: git-http-push failed

if I enter different credentials I get the following expected error:
fatal: Authentication failed for 'http://abc.mydomain.com/groupname/signup.git/'

I have searched the internet far and wide for the last 2 days and I can't get a solution to this.
How can I resolve this?

Thanks in advance,

Amir
