Git clone ssh - Permission denied (publickey) doesn't clone a repository?

Question

git

Created a repository on my remote server.
I connect from my user to the server by key - everything is ok.
When trying to git clone:

sudo git clone [email protected]:/var/www/domain/my.git
Cloning into 'my'...
Permission denied (publickey).
fatal: Could not read from remote repository.

I can't understand - it turns out to enter the server by key, but when using git it rejects.
Tired of looking for answers.

Answer 1

sudo ssh [email protected] -- can you login?
Hinting at a solution to the problem: why avoid sudo?

Answer 2

Check directory permissions
