/var/log/secure should give you an indication of why the key is not being
accepted.  But you may have to turn the log level up.

But initial thoughts are that it is likely to be a permissions problem the
~deploy/.ssh directory needs to be 700
If you are using SE Linux then you may want to try doing restorecon -Rv
~deploy/.ssh
