ssh - git push failing in gitlab

Question

1. I have installed Gitlab in /home/myuser/gitlab.
   1. I created a rep test
   2. Following instructions, I added a remote git@localhost:root/testing.git

I found that there was a problem with my ssh connect. Here's my /home/myhome/.ssh/config file

Host mylocalhost
Hostname localhost
User git
IdentityFile /home/myuser/.ssh/id_rsa

When I run git push -u origin master I am asked to enter my passphrase. But, immediately after I get this message

Connection closed by ::1

fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

Where am I going wrong ? Is this my ssh connection

Update : I stopped sshd and the ran sshd -d (in my /home/myhome) and then ssh -T mylocalhost, I got in the ssh -d output

Btw, each time I run some git command, I get the message

ssh: Could not resolve hostname mylocalhost: nodename nor servname provided, or not known
fatal: Could not read from remote repository.

Update 2

When I run ssh mylocalhost, I have the good message Welcome to GitLab, Administrator!. But then, I get the following input
