I followed the instructions here in order to set up a private git server on my Amazon EC2 instance. However, I am having problems when trying to SSH into the git account. Specifically, I get the error "Permission denied (publickey)."
Here are the permissions of my files/folders on the EC2 server:
drwx------ 4 git git 4096 Aug 13 19:52 /home/git/
drwx------ 2 git git 4096 Aug 13 19:52 /home/git/.ssh
-rw------- 1 git git 400 Aug 13 19:51 /home/git/.ssh/authorized_keys
Here are the permissions of my files/folders on my own computer:
drwx------ 5 CYT staff 170 Aug 13 14:51 .ssh
-rw------- 1 CYT staff 1679 Aug 13 13:53 .ssh/id_rsa
-rw-r--r-- 1 CYT staff 400 Aug 13 13:53 .ssh/id_rsa.pub
-rw-r--r-- 1 CYT staff 1585 Aug 13 13:53 .ssh/known_hosts
When checking my logs in /var/log/secure, I used to get the following error message every time I tried to SSH:
Authentication refused: bad ownership or modes for file /home/git/.ssh/authorized_keys
However, after making a few permission changes, I no longer get this error message. Despite this, I am still getting the "Permission denied (publickey)." message every time I try to SSH.
The command I am using to SSH is ssh -T git@my-ip.
Here is the full log I get when I run ssh -vT

I have spent a few hours going through threads on various sites, including SO and SF, looking for a solution. It seems that the permissions for my files are all okay, but I just can't figure out the problem. Any help would be greatly appreciated.
Edit:
EEAA: Here are the outputs you requested:
$ getent passwd git
git:x:503:504::/home/git:/bin/bash
$ grep ssh ~git/.ssh/authorized_keys | wc -l
grep: /home/git/.ssh/authorized_keys: Permission denied
0
